We control most flags via Starlark and therefore limit configuration
options via `tsconfig` to a minimum. We do not intend to support the
enabled block types option via Starlark, so this commit allows for
the option to be picked up.
(This is useful for benchmarking the new control flow blocks).

In Devtools bar chart we can see the total time for all the directive instances in one change detection run.
This PR changes the bar chart to display the total count and time for all directive instances instead of showing the time for each directive instance separately in one change detection run.

This change simply flip the flag which enables using the deps tracker in JIT compilation (the logic is already implemented in a previous PR). Some tests which depend on the old JIT implementation (e.g., patching the scope info into the type) are modified accordingly.
PR Close#51415
Using verification helpers such as `isComponent` may trigger JIT compilation. Now in some tests such compilation is made purposely to fail, and so in such cases any reference to the `depsTracker.clearScopeCacheFor` method will cause the exception to be thrown earlier than expected which results in teh test failure. Such scenario is the case in the next commit when we enable using the deps tracker in the jit compilation. Note that such failure is only for the framework tests and is a very edge case. The tests in downstream apps will not lead to such scenario of failure at all.

The `setupTestingRouter` function is a factory function for creating a
new instance of the `Router`. This function is effectively a no-op.
Developers should use `RouterModule.forRoot` or `provideRouter` in tests
instead.
BREAKING CHANGE: The `setupTestingRouter` function has been removed. Use
`RouterModule.forRoot` or `provideRouter` to setup the `Router` for
tests instead.

This PR moves the Observable subscription of toSignal outside of the
reactive context. As the result the toSignal calls are allowed in the
computed, effect and all other reactive consumers.
This is based on the reasoning that we already allow signals creation
in a reactive context. Plus a similar change was done to the async pipe
in the https://github.com/angular/angular/pull/50522Fixes#51027

Certain tools in g3 which dynamically bootstrap a component (e.g., custom routers) simply swallow the exception coming from bootstrapping the component and show an empty outlet. Such cases are very difficult to debug as the dev has no clue why the component was not rendered. As bad as this pattern is, fixing all such tools for a better error handling is beyond the scope of our effort. Instead, in this change we print the error messages coming from calculating component dependencies (part of component rendering) to the console for a better visibility into the error. This change only affects local compilation where the component dependencies are calculated in runtime. This change can potentially shed light into many failures of local compilation in g3.

Standalone component need to include the imported NgModules as part of their dependencies in order to be able to use the injection tokens coming from these NgModules. To do so, in this change the imported NgModules are included in the standalone component compilation scope.
PR Close#51819
Currently the compiler in local mode assumes that the standalone component imports are array expressions. This is not always true as they can be const variables as well. This change allow non-array expressions for standalone component imports field and passes that expression to the downstream tools such as deps tracker to compute the component's deps in runtime.
PR Close#51819
Current implementation assumes that NgModule imports/exports fields are always arrays and thus it concats them for the injector definition. But this is not always the case and imports/exports could be non-arrays such as const variable. Such pattern happens in g3 and so must be addressed.

Adds support for template type checking of the `track` expression of a `for` loop block. Tracking expressions are treated as any other expression for type checking, however we have some special validation that doesn't allow them to access template variables and local references.

Adds support for template type checking inside `for` blocks. It is implemented by generating a JS `for...of` statement inside the TCB. The various loop variables (e.g. `$index`) are implemented by declaring a local number variable.

Adds support for template type checking inside `if` blocks. It is implemented by generating a JS `if` statement inside the TCB which allows us to do type narrowing of the expression. The `as` parameter is implemented by declaring a variable inside the `if` statement.

The browserUrlTree is only used to support the onSameUrlNavigation: 'ignore' logic. We can achieve this functionality without having this state tracked inside the Router. Instead, we can re-examine what ignore means: We don't want to rerun the matching logic, guards, or resolvers when we already know that nothing is changing.
Outside of the "navigated", there are two things that constitute a "change":
1. The browser URL might change. Because of skipLocationChange, the browser URL might not always match the internal state of the Router (we can navigate to a path but skip updating the browser URL). If we're navigating to a place that would change the browser URL, we should process the navigation. Theoretically, all we need to really do is update the browser URL instead of processing the whole navigation w/ guards, redirects, and resolvers. But this doesn't matter that much because the default value for runGuardsAndResolvers will skip all of this anyways.
2. The internal state of the Router might change. That is, we're navigating to a new path and may or may not be updating the updating the browser URL.
If either of the above are true, we process the navigation. If both are false, we aren't changing anything so we can safely ignore the navigation request (as long as onSameUrlNavigation === 'ignore').
Why is this change important?
* Simplification of Router internals. The Router has a lot of special case handling and one-offs to handle a limited set of scenarios. Removing these when possible makes the code easier to follow

Adds a utility to the `BoundTarget` that helps with resolving which element a deferred block is pointing to. We need a separate method for this, because deferred blocks have some special logic for where the trigger can be located.

When the `TargetBinder` was written, the only embedded-view-based nodes were templates, but now we have `{#if}`, `{#switch}` and `{#defer}` which have similar semantics. These changes rework the binder to account for the new nodes.

Content project allows the content to specify its own selector for matching against content projection slots, using the `ngProjectAs` special attribute. We can now treat this attribue specially, and generate the appropriate flag in the consts array, followed by the parsed CSS selector.
PR Close#51544
Supporting content projection requires us to emit three new kinds of output:
1. An `ngContentSelectors` field on the component metadata, which points to an array in the constant pool with all of the `select` attributes from `<ng-content>` elements.
2. One `projectionDef` instruction at the beginning of each root view template function for a component. That `projectionDef` points to a constant pool expression, which contains *parsed* selectors for all `<ng-content>` elements in the root's entire view tree.
3. A `projection` instruction for each `<ng-content>` slot in the view tree. These each get a data slot, a monotonically increasing "content slot", and a pointer to the tag's attributes in the component const array.
We support the first two features entirely within a new compilation phase.
The third feature, collection of processed attributes, is a bit trickier. We now treat `<ng-content>` tags as element-like ops, and use the normal attribute ingestion pipeline to process any attributes, and assign the appropriate `ConstIndex`.
**Note**: We also split up a number of the tests into two expectations files, one for the view functions, and one for other const listerals from the constant pool. This is because `TemplateDefinitionBuilder` emits the literals in a quirky order (mixed in with the view functions) due to how it lazily generates view functions. Our eager ordering is totally different, but by splitting the expectations, we can still share the same tests with `TemplateDefinitionBuilder`.

The new built-in control flow design includes calls to the `template` instruction with fewer arguments. This was previously handled implicitly, but it's more extensible to add an explicit flag to the template op to handle this case.

Although there are several pages, only `service-worker-getting-started.md` has an example.
That example code was migrated.
Worked around the few references to NgModule.
Other changes as follows:
**Revised "Getting Started"**
The original service worker example page (`service-worker-getting-started.md`) is full of holes! I don’t know how anyone got this working just by following this page
- it doesn’t tell you where to get the example (and it isn’t generated by AIO)
- it doesn’t tell you that ng serve doesn’t support service worker apps
- it mentions http-server in passing but not what that is or where to get it.
- several commands tell you to supply the “project-name” but (a) it doesn’t tell you how to find that name and (b) you never actually have to provide a name at all. That includes on the command that gets http-server going.
**Hid section on `ngsw-config` tool**
Hid the discussion of the `ngsw-config` tool in `service-worker-config.md` because
(a) the command invoke it didn't seem to work and (b) it referenced `<project-name>`
without explaining what that is or where to find it.
Left the hidden text in the page in case someone wants to do something about this.
Meanwhile, you seem to be able to edit the `ngsw-config.json` and then rebuild.
That should suffice.
**Disabled E2E**
The AIO CI will no longer attempt to run the (thin) E2E tests.
These tests could lightly test the app with the dev server but couldn't test the Service Worker aspects; that would require launching the app with something other than `ng serve` and the AIO CI is not set up for that.
The existing tests appeared to pass when run locally with the dev server.
However, only one of them actually ran; test runner reported.
"There were tests whose specified size is too big."
Decided to bypass E2E testing of this project for now.

The `malformedUriErrorHandler` is used as a recovery mechanism for when the `UrlSerializer`
throws an error when parsing a URL string. If custom error handling is
desired for this, it should instead be done inside the
`UrlSerializer.parse` method itself. There's no reason to have an entire
feature option built around what can otherwise just be `try...catch`.
BREAKING CHANGE: `malformedUriErrorHandler` is no longer available in
the `RouterModule.forRoot` options. URL parsing errors should instead be
handled in the `UrlSerializer.parse` method.

Currently deps tracker includes the exported scope of the exported NgModule only in the exported scope of that NgModule. This is in agreement with what AoT does today. But JIT diverges from this behavior by including these exported scopes into the compilation scope as well. Since deps tracker is going to be used for both AoT (local compilation mode) and JIT, the question might be which behavior the deps tracker should follow? Today it follows the AoT one, but it breaks some tests in Google which seem to depend on this behavior of JIT. So it is better to migrate deps tracker to what JIT does. This leads to a wider compilation scope in local compilation compared to full compilations, but it won't break any existing thing.
