Adds the implementation of the following new instructions:
* `declareLet` - creation-time instruction that initializes the slot for a let declaration.
* `storeLet` - update-time instruction that stores the current value of a let declaration.
* `readContextLet` - instruction that reads the stored value of a let declaration from a different view.
On top of the instructions, it also introduces a new `LetDeclaration` TNode type.
The new TNode is nececessary for DI to work correctly in pipes inside the let expression,
as well as for proper hydration support.

When collecting nodes from the DOM for hydration, we need to treat nodes with paths (e.g. content projection) as the new root for all subsequent elements, not just the next one.
Additionally, when using content projection it's possible for translated content to become disconnected, e.g. when it doesn't match a selector and there isn't a default. We need to handle such cases by manipulating the disconnected node data associated with hydration as usual.

This commit adds extra checks to handle a situation when an application has no events configured, but the Event Replay feature was enabled. This situation can happen when some routes in an application are mostly static, when other routes are more interactive.

These changes integrate let declarations into the template pipeline. This involves a few operations:
* Producing a `declareLet` instruction call at creation time to initialize the declaration.
* Producing a `storeLet` instruction call in the place of the let declaration, including the necessary `advance` calls beforehand.
* For let declarations used within their declaration view, moving the `const` to be placed right after the `storeLet` call to ensure the their value has been computed.
* For let declarations that are _only_ used in their declaration view, removing the `storeLet` call and inlining the expression into the constant statement.

Router's `OutletInjector` required a special handling in cases when `@defer` is used, see https://github.com/angular/angular/pull/55374 for additional info. As a result, the `ChainedInjector` that represents an `OutletInjector` instance is currently exposed via `getInjectorResolutionPath` function. This creates a problem, because other debug APIs used by DevTools can not interact with `ChainedInjector`s. This commit updates the logic around `getInjectorResolutionPath` utility to avoid exposing `OutletInjector`in the resolution path.

This allows for helpers like the following to work intuitively for all
types of "input fields". It also establishes the intended mental
philosophy that a model is both an input and an output.
```ts
/** Unwraps all signal input properties. */
export type UnwrapSignalInputs<T> = {
[K in keyof T]: T[K] extends InputSignalWithTransform<any, infer WriteT>
? WriteT
: T[K];
};

This commit updates hydration serialization logic to handle a case when the `withI18nSupport()` call is not present for an application that has a component that uses i18n blocks. Note: the issue is only reproducible for components that also inject `ViewContainerRef`, since it triggers a special serialization code path.

This makes events bubble! This change also contains changes to
dispatcher and event_dispatcher to make replay synchronous,
so that we avoid odd timing issues. This can be split out though.
Lastly, we have one cleanup change to move the mapping from
event type to functions on the element itself.
PR Close#56036
Previously, the event replay serialization logic was located before we verify that a `TNode` exists. `TNode`s may not exist in `tView.data` array in several cases, including cases when there is a local ref used on an element: in this case an extra slot in `LView` contains a reference to the same element and `TNode` is not needed. This commit moves the event replay serialization logic a bit lower, after we check for TNode presence.

Users may be using zoneless, but are still loading Zone.js in which case they won't get the full benefits like reduced bundle size. These changes detect such a case and log a warning.
PR Close#55769
Because exhaustive checks traverse the whole tree regardless of the
dirty state, it breaks some expectations around how change detection
should be running. When a view has transplanted views, it
unconditionally marks all ancestors for traversal, assuming this is fine
because the loop will just traverse them and find nothing dirty.
However, exhaustive checkNoChanages actually refreshes everything during
traversal.
This update ensures the exhaustive check only does a single pass and
also prevents some unnecessary marking of transplanted views for
refresh since we know they're going to be reached.

Developers may want to enable zoneless for all tests by default by
adding the zoneless provider to `initTestEnvironment` and then
temporarily disabling it for individual tests with the zone provider
until they can be made zoneless compatible.

Angular has long had the ability to use different interpolation delimiters
(by default `{{` and `}}`). This concept was copied over from AngularJS,
where AngularJS syntax is included in HTML sent over the network to the
browser. Occasionally developers would use SSR frameworks which _also_ have
interpolation syntaxes of their own, so there was a need to change the
delimiters used by AngularJS to avoid conflicts.
Since Angular templates are always processed by our compiler and the
interpolation characters are never processed by other systems first, this
option is vestigial in Angular and only increases the complexity of our
parser.
DEPRECATED: `@Component.interpolation` is deprecated. Use Angular's
delimiters instead.

The first test asserts that bubbling does not work right now.
The second asserts that stopPropagation works, which should pass when test #1 passes too.
The third test asserts properties about the events passed to the event handler.
THe fourth test asserts that mouse events do not translate to jsaction nor help emit the jsaction binary. This required a change in code to make this pass.

This commit adds a feature that is useful for determining if an
application is zoneless-ready. The way this works is generally only
useful right now when zoneless is enabled. Some version of this may be useful in
the future as a general configuration option to change detection to make
`checkNoChanges` pass always exhaustive as an opt-in to address #45612.
Because this is an experimental, debug-only feature, it is okay to merge
during the RC period.

Rather than attempting to use the native timing functions, this commit
simplifies the logic significantly by using the global timer functions
as they are, either patched or unpatched. When Zone is defined, we run
the timers in the root zone. This has more predictable behavior and
timing than (a) using both patched and unpatched versions of timers in
different places (b) trying to get an unpatched timer and failing due to
environment specifics and patches that aren't ZoneJS.
