Currently unless a listener inside of an embedded view tries to reference something from the parent view, or if the reference is a local ref, we don't generate the view restoration instructions and we allow for the value to be picked up from the context object in the function parameters. The problem is that the listener is only run during creation mode and the context object may have been swapped out afterwards.
These changes fix the issue by always generating the view restoration instructions for listeners inside templates.
Fixes#42698.

When `TestBed.compileComponents` is called under ViewEngine, we kick off a compilation and return a promise that resolves once the compilation is done. In most cases the consumer doesn't _have_ to await the returned promise, unless their components have external resources.
The problem is that the test could be over by the time the promise has resolved, in which case we still cache the factory of the test module. This becomes a problem if another compilation is triggered right afterwards, because it'll see that we still have a `_moduleFactory` and it won't recreate the factory.
These changes resolve the issue by saving a reference to the module type that is being compiled and checking against it when the promise resolves.
Note that while this problem was discovered while trying to roll out the new test module teardown behavior in the Components repo (https://github.com/angular/components/pull/23070), it has been there for a long time. The new test behavior made it more apparent.

As of ES2021, JavaScript allows using underscores as separators inside numbers, in order to make them more readable (e.g. `1_000_000` vs `1000000`). TypeScript has had support for separators for a while so these changes expand the template parser to handle them as well.

If an implcit receiver is accessed in a listener inside of an `ng-template`, we generate some extra code in order to ensure that we're assigning to the correct object. The problem is that the logic wasn't covering keyed writes which caused it to write to the wrong object and throw an assertion error at runtime.
These changes expand the logic to cover keyed writes.
Fixes#41267.

We currently have two long-standing issues related to how `TestBed` tests are torn down:
1. The dynamically-created test module isn't going to be destroyed, preventing the `ngOnDestroy` hooks on providers from running and keeping the component `style` nodes in the DOM.
2. The test root elements aren't going to be removed from the DOM. Instead, they will be removed whenever another test component is created.
By themselves, these issues are easy to resolve, but given how long they've been around, there are a lot of unit tests out there that depend on the broken behavior.
These changes address the issues by introducing APIs that allow users to opt into the correct test teardown behavior either at the application level via `TestBed.initTestEnvironment` or the test suite level via `TestBed.configureTestingModule`.
At the moment, the new teardown behavior is opt-in, but the idea is that we'll eventually make it opt-out before removing the configuration altogether.

Introduces a few Starlark macros for running the new Bazel
CLDR generation tool. Wires up the new tool so that locales
are generated properly. Also updates the existing
`closure-locale` file to match the new output generated by the Bazel tool.
This commit also re-adds a few locale files that aren't
generated by CLDR 37, but have been accidentally left in
the repository as the Gulp script never removed old locales
from previous CLDR versions. This problem is solved with the
Bazel generation of locale files, but for now we re-add these
old CLDR 33 locale files to not break developers relying on these
(even though the locale data indicies are incorrect; but there might
be users accessing the data directly)

Previously the autoRegisterModuleById registration was marked with noSideEffects wrapper to ensure that we don't end up retaining all NgModules.
However the return value was not referenced by anything, so closure compiler removed it because it determined that this code has no side effects and is not referenced by anyone.
This issue affects apps that use Closure Compiler and also rely on https://angular.io/api/core/getModuleFactory to retrieve factories by ID. This combination is used heavily in google3, especially in Pantheon.

The `NO_ERRORS_SCHEMA` schema can be used to ignore errors related to unknown elements or properties, but since it suppresses these errors it may also hide real problems in a template. This commit updates the `NO_ERRORS_SCHEMA` docs to mention that.

When a `trackBy` function is used that accepts a supertype of the iterated
array's type, the loop variable would undesirably be inferred as the supertype
instead of the array's item type. This commit adds an inferred type parameter
to `TrackByFunction` to allow an extra degree of freedom, enabling the
loop value to be inferred as the most narrow type.

With this change we add a migration to replace the deprecated shadow-piercing selector from `/deep/` with deprecated but recommended `::ng-deep`.
The main motivation for this change is that the CSS optimizer CSSNano which is used by the Angular CLI no longer supports this non standard selector and causes build time errors due to the selector being minified incorrectly. However, CSSNano does support the recommended deprecated `::ng-deep` selector.

We skip event listeners on non-element host nodes (e.g. `ng-container` or `ng-element`), because they don't map to a DOM node so there's nothing to bind the event to. The problem is that this also prevents listeners bound to global targets from being bound.
These changes add an extra condition to allow for the event to be bound if it has a custom event target resolver.
