This commit adds a provider function that allows developers to configure
the `NgZone` instance for the application. In the future, this provider
will be used for applications to specifically opt-in to change detection
powered by ZoneJS rather than it being provided by default.
This API does _not_ specifically provide support for developers to define their own
`NgZone` implementation or opt in to `NoopNgZone` directly. Both of
these are possible today, but are effectively unsupported (applications
that use these are left to their own devices to run change detection at
the appropriate times). That said, developers can still use DI in
`bootstrapApplication` to provide an `NgZone` implementation instead,
it's just not specifically available in the
`provideZoneChangeDetection` function.

When having a recursive circle of imports on standalone components, `queueTypesFromModulesArrayRecur` triggered a `Maximum call stack size exceeded` error.
This commit fixes this.

This commit moves the providers for `NgZone`-based change detection to a
single provider function. This function is currently called by default
in all places where `NgZone` was provided
(`bootstrapApplication`, `bootstrapModule`, and `TestBed`).
When we want to make Angular applications zoneless by default, we
can make a public provider method that has to be used in order to enable
the zone change detection features. When this method is not called,
Angular would use `NoopNgZone` by default and not initialize any
subscriptions to the `NgZone` stability events.
Side note: There are actually two places that `NgZone` is provided for `TestBed`
(providers in `compileTestModule` and `BrowserTestingModule`). This
likely doesn't need to be in both locations.

TestBed.overrideProvider should include `multi` support in its type. The
underlying implementation already supports it, as documented by the
tests which are currently casting the override to `any` to get around
the bad type.

This commit adds `TestBed.runInInjectionContext` which is equivalent to
`TestBed.inject(EnvironmentInjector).runInContext`. This function will
help make tests for functions which call `inject` from `@angular/core` a

This commit modifies `R3Injector` and other code in Angular that deals with
providers, to handle `EnvironmentProviders` objects as well as normal
`Provider` types. There is no user-visible impact to this change, but it
prepares the core of the DI system for the introduction of
`EnvironmentProviders` as a public feature.

This commit applies the changes similar to the ones performed for the `inject()` function in df246bb235.
The `TestBed.inject` function is updated to use previously added object-based API for options: now the flags argument supports passing an object which configures injection flags.
DEPRECATED:
The bit field signature of `TestBed.inject()` has been deprecated, in favor of the new options object.

Adds support for TypeScript 4.8 and resolves some issues that came up as a result of the update.
Most of the issues came from some changes in TypeScript where the `decorators` and `modifiers` properties were removed from most node types, and were combined into a single `modifiers` array. Since we need to continue supporting TS 4.6 and 4.7 until v15, I ended up creating a new `ngtsc/ts_compatibility` directory to make it easier to reuse the new backwards-compatible code.

This commit performs various refactoring of the TestBed code to better align interfaces and implementation. The implementation class is also renamed from `TestBedRender3` -> `TestBedImpl`, but the public API name has not changed.
Note: as a part of this change, the TestBed interface became more consistent and typings for multiple methods were updated to account for the fact that the TestBed reference is returned. This was always a runtime behavior of TestBed, which was not reflected in few places in type.
PR Close#46635
Prior to this commit, the TestBed logic erroneously tried to apply provider overrides to standalone pipes that were imported in an NgModule. This commit updates the logic to recognize types that may have a scope (an NgModule or a standalone component) and skip other types while applying provider overrides recursively.
PR Close#46407
Prior to standalone components, the `applyProviderOverridesToModule` method was used exclusively for NgModules. With standalone, its scope was expended to include standalone components as well. This commit renames the method to `applyProviderOverridesInScope` to better reflect this + also renames a field that refers to a set that contains already overridden types.

PR Close#45999
Previously, the code in TestBed didn't take into account the fact that the `cmp.dependencies` array after the AOT compilation might contain regular (NgModule-based) Components/Directive/Pipes. As a result, some NgModule-specific code paths were invoked for non-NgModule types, thus leading to errors.
This commit updates the code to handle AOT-compiled structure of standalone components correctly.

This commit updates the NgModule logic to account for a case when a type has more than one generated def. This is a common situation for NgModules which have at least two: ɵmod and ɵinj. Previously, the second def was not stored before applying overrides, thus leaving it modified after the test, leaking the state as a result. This fix ensures that we store all defs before applying any overrides.

Adds support for TypeScript 4.7. Changes include:
* Bumping the TS version as well as some Bazel dependencies to include https://github.com/bazelbuild/rules_nodejs/pull/3420.
* Adding a backwards-compatibility layer for calls to `updateTypeParameterDeclaration`.
* Making `LView` generic in order to make it easier to type the context based on the usage. Currently the context can be 4 different types which coupled with stricter type checking would required a lot of extra casting all over `core`.
* Fixing a bunch of miscellaneous type errors.
* Removing assertions of `ReferenceEntry.isDefinition` in a few of the language service tests. The field isn't returned by TS anymore and we weren't using it for anything.
* Resolving in error in the language service that was caused by TS attempting to parse HTML files when we try to open them. Previous TS was silently setting them as `ScriptKind.Unknown` and ignoring the errors, but now it throws. I've worked around it by setting them as `ScriptKind.JSX`.

BREAKING CHANGE:
Since Ivy, TestBed doesn't use AOT summaries. The `aotSummaries` fields in TestBed APIs were present, but unused. The fields were deprecated in previous major version and in v14 those fields are removed. The `aotSummaries` fields were completely unused, so you can just drop them from the TestBed APIs usage.
PR Close#45487
Angular contains an NgModule registry, which allows a user to declare
NgModules with string ids and retrieve them via those ids, using the
`getNgModuleById` API.
Previously, we attempted to structure this registration in a clever fashion
to allow for tree-shaking of registered NgModules (that is, those with ids).
This sort of worked due to the accidental alignment of behaviors from the
different tree-shakers involved. However, this trick relies on the
generation of `.ngfactory` files and how they're specifically processed in
various bundling scenarios. We intend to remove `.ngfactory` files, hence
we can no longer rely on them in this way.
The correct solution here is to recognize that `@NgModule({id})` is
inherently declaring a global side-effect, and such classes should not
really be eligible for tree-shaking in the first place. This commit removes
all the old registration machinery, and standardizes on generating a side-
effectful call to `registerNgModuleType` for NgModules that have ids.
There is some risk here that NgModules with unnecessary `id`s may not
tree-shake as a result of this change, whereas they would have in previous
circumstances. The fix here should be to remove the `id` if it's not needed.
Specifying an `id` is a request that the NgModule be retained regardless of
any other references, in case it is later looked up by string id.
PR Close#45024
Previously, some NgModules that were added to the delayed scoping queue, never got removed from the queue before unit test execution. That resulted in some components (declared in those NgModules) missing their scope (which components/directives/pipes were matched).
This commit adds the logic to invoke delayed scoping queue flushing before starting a test to avoid missing/incomplete scopes for Components used in a test.

This commit removes the View Engine runtime. Itself, this change is
relatively straightforward, but it represents the final step in a multi-year
journey. It's only possible due to the hard work of many current and former

PR Close#43884
This commit removes most tests that were designated as only covering View
Engine code. It also removes tag filters from CI and local commands to run
tests.
In a few cases (such as with the packages/compiler tests), this tag was
improperly applied, and certain test cases have been added back running in
Ivy mode.
This commit also empties `@angular/compiler/testing` as it is no longer
necessary (this is safe since compiler packages are not public API). It can
be deleted in the future.

The TestBed APIs to override metadata would crash when the metadata
contained objects with cyclic references. Metadata overrides use the
JSON serialized representation of a value to compare objects, which
throws an error if the value has cyclic references. This commit avoids
the error by replacing multiple occurrences of the same object using
a unique string representation for the object.

Adds support for TypeScript 4.4. High-level overview of the changes made in this PR:
* Bumps the various packages to `typescript@4.4.2` and `tslib@2.3.0`.
* The `useUnknownInCatchVariables` compiler option has been disabled so that we don't have to cast error objects explicitly everywhere.
* TS now passes in a third argument to the `__spreadArray` call inside child class constructors. I had to update a couple of places in the runtime and ngcc to be able to pick up the calls correctly.
* TS now generates code like `(0, foo)(arg1, arg2)` for imported function calls. I had to update a few of our tests to account for it. See https://github.com/microsoft/TypeScript/pull/44624.
* Our `ngtsc` test setup calls the private `matchFiles` function from TS. I had to update our usage, because a new parameter was added.
* There was one place where we were setting the readonly `hasTrailingComma` property. I updated the usage to pass in the value when constructing the object instead.
* Some browser types were updated which meant that I had to resolve some trivial type errors.
* The downlevel decorators tranform was running into an issue where the Closure synthetic comments were being emitted twice. I've worked around it by recreating the class declaration node instead of cloning it.

When using `TestBed.overrideComponent`, the overridden component would
incorrectly lose access to its NgModule's declaration scope if the
NgModule had been imported into the testing NgModule as a
`ModuleWithProviders`, e.g. using a `forRoot` call.
The issue occurred as the `TestBed` compiler did not consider NgModules
that had been imported as a `ModuleWithProviders` when associating
NgModules with component overrides. This caused the overridden component
to be compiled standalone, meaning that it does not have access to
its NgModule's declarations. This commit extends the logic for
traversing the NgModule graph to also consider `ModuleWithProviders`
imports.
