This validates the `tsconfig.json` options for extended template diagnostics. It verifies:
* `strictTemplates` must be enabled if `extendedDiagnostics` have any explicit configuration.
* `extendedDiagnostics.defaultCategory` must be a valid `DiagnosticCategoryLabel`.
* `extendedDiagnostics.checks` keys must all be real diagnostics.
* `extendedDiagnostics.checks` values must all be valid `DiagnosticCategoryLabel`s.
These include new error codes, each of which prints out the exact property that was the issue and what the available options are to fix them.
It does disallow the config:
```json
{
"angularCompilerOptions": {
"strictTemplates": false,
"extendedDiagnostics": {
"defaultCategory": "suppress"
}
}
}
```
Such a configuration is technically valid and could be executed, but will be rejected by this verification logic. There isn't much reason to ever do this, since users could just drop `extendedDiagnostics` altogether and get the intended effect. This is unlikely to be a significant issue for users, so it is considered invalid for now to keep the implementation simple.

The `defaultCategory` option is used for any extended template diagnostics which do not have any specific category specified for them. It defaults to `warning`, since that is the most common behavior expected for users. This provides an easy way for users to promote all diagnostics to errors or suppress all diagnostics.

This includes a mapping of extended template diagnostics to their associated diagnostic category. It is generated from the list of diagnostic names, so the list should always be implicitly kept up to date. Usage looks like:
```json

"checks": {
"invalidBananaInBox": "error",
"nullishCoalescingNotNullable": "suppress"

The enum of extended template diagnostic names allows a global registry of first-party diagnostics with a developer-friendly string name which can be used for configuration. This name is used in the new `TemplateCheckFactory` to bind the name to a particular `ErrorCode` and make both available *before* constructing the actual template check, which is necessary to configure it appropriately.

In certain scenarios, the compiler may have crashed with an
`Unable to write a reference` error which would be particularly hard
to diagnose. One of the primary reasons for this failure is when the
`rootDir` option is configured---typically the case for libraries---
and a source file is imported using a relative import from an external
entry-point. This would normally report TS6059 for the invalid relative
import, but the crash prevents this error from being surfaced.
This commit refactors the reference emit logic to result in an explicit
`Failure` state with a reason as to why the failure occurred. This state
is then used to report a `FatalDiagnosticException`, preventing a hard
crash.

This reverts commit cdf50ff931.
Reverting as this needs a little more work on the documentation side, plus
the `export declare interface` syntax in `model.ts` might have unintended
side effects in g3.
This implementation change was originally proposed as part of Typed Forms, and will have major consequences for that project as described in the design doc. Submitting it separately will greatly simplify the risk of landing Typed Forms. This change should have no visible impact on normal users of FormControl.

* The `TransitionAnimationEngine` had a fallback where it would store classes directly on a node if it doesn't have a `classList`. Presumably this is to support old browsers or if an animation is set on something like `ng-container`. This information was never used for anything since `containsClass` was never called. These changes simplify the logic to just a null check.
* Deprecates the `AnimationDriver.matchesElement` method, because it was only used in one place which can be replaced with `classList.contains`. We can't remove the method completely, because `AnimationDriver` is a public API. We also can't turn it into a method on the base class in order to remove it from the sub-classes, because it can break apps using `noImplicitOverride` while extending `AnimationDriver`.

Currently the `HttpClient` always wraps errors from XHR requests, but
the underlying errors are always of type `ProgressEvent`, or don't have
a native error if the status code is just indicating failure (e.g. 404).
This behavior does not match in the `TestRequest` class provided by
`@angular/common/http/testing` where errors are considered being
of type `ErrorEvent`. This is incorrect because `ErrorEvent`s provide
information for errors in scripts or files which are evaluated. Since
the `HttpClient` never evaluates scripts/files, and also since XHR requests
clearly are documented to emit `ProgressEvent`'s, we should change the
`TestSupport` to retrieve such `ProgressEvent`'s instead of incompatible
objects of type `ErrorEvent`.
In favor of having a deprecation period, we keep supporting `ErrorEvent`
in the `TestRequest.error` signature. Eventually, we can remove this
signature in the future.

DEPRECATION:
In ViewEngine, [JIT compilation](https://angular.io/guide/glossary#jit) required special providers (like `Compiler`, `CompilerFactory`, etc) to be injected in the app and corresponding methods to be invoked. With Ivy, JIT compilation takes place implicitly if the Component, NgModule, etc have not already been [AOT compiled](https://angular.io/guide/glossary#aot). Those special providers were made available in Ivy for backwards-compatibility with ViewEngine to make the transition to Ivy smoother. Since ViewEngine is deprecated and will soon be removed, those symbols are now deprecated as well:
- `ModuleWithComponentFactories`
- `Compiler`
- `CompilerFactory`
- `JitCompilerFactory`
- `NgModuleFactory`
Important note: this deprecation doesn't affect JIT mode in Ivy (JIT remains available with Ivy).

This commit introduces a new `SwUpdate#versionUpdates` observalbe, which provides more granular
information about Service Worker version updates than the already existing `SwUpdate#available`
observable.
The new events emitted by `SwUpdate#versionUpdates` basically add the possibility for application to
get notified if a new version is available on the server (not yet downloaded) and if an installation
of a new version failed.
Closes#39840
DEPRECATED: The `SwUpdate#availalbe` observable is deprecated.
The new `SwUpdate#versionUpdates` observable provides the same information and more. Therefore, it
is possible to rebuild the same behavior as `SwUpdate#availalbe` using the events emitted by
`SwUpdate#versionUpdates` and filtering for `VersionReadyEvent` events.
As a result, the `SwUpdate#availalbe` observable is now redundant.

Previously `activateUpdate` and `checkForUpdate` returned `Promise<void>`, which did not provide any
information of the actual outcome of the operation. Developers needed to subscribe to a
corresponding observable to obtain the outcome.
With this commit `SwUpdate#activateUpdate` will return `Promise<boolean>` which resolves to `true` if
an update was activated, to `false` if no new version is available and rejects in case of any error.
`SwUpdate#checkForUpdate` also returns a `Promise<boolean>` which resolves to `true` if an update is available, to `false` if no update was found and rejects in case of any error.
Closes#39840
BREAKING CHANGE: The return type of `SwUpdate#activateUpdate` and `SwUpdate#checkForUpdate` changed to `Promise<boolean>`.
Although unlikely, it is possible that this change will cause TypeScript type-checking to fail in
some cases. If necessary, update your types to account for the new
return type.
DEPRECATED: The `SwUpdate#activated` observable is deprecated.
The `SwUpdate#activated` observable only emits values as a direct response to calling
`SwUpdate#activateUpdate()` and was only useful for determining whether the call resulted in an
update or not. Now, the return value of `SwUpdate#activateUpdate()` can be used to determine the
outcome of the operation and therefore using `SwUpdate#activated` does not offer any benefit.

When compiling your application using the AOT compiler, your templates
are type-checked according to a certain strictness level. Before Angular 9
there existed only two strictness levels of template type checking as
determined by [the `fullTemplateTypeCheck` compiler option](guide/angular-compiler-options).
In version 9 the `strictTemplates` family of compiler options has been
introduced as a more fine-grained approach to configuring how strict your
templates are being type-checked.
The `fullTemplateTypeCheck` flag is being deprecated in favor of the new
`strictTemplates` option and its related compiler options. Projects that
currently have `fullTemplateTypeCheck: true` configured can migrate to
the following set of compiler options to achieve the same level of
type-checking.

PR Close#37284
PR Close#43280
The current behavior of `routerLink` for `null` and `undefined` inputs is to treat
the input the same as `[]`. This creates several unresolvable issues with
correctly disabling the links because `commands = []` does _not_ behave the same
as disabling a link. Instead, it navigates to the current page, but will also
clear any fragment and/or query params.
The new behavior of the `routerLink` input will be to completely disable navigation
for `null` and `undefined` inputs. For HTML Anchor elements, this will also mean
removing the `href` attribute.
Fixes#21457Fixes#13980Fixes#31154
BREAKING CHANGE:
Previously `null` and `undefined` inputs for `routerLink` were
equaivalent to empty string and there was no way to disable the link's
navigation.
In addition, the `href` is changed from a property `HostBinding()` to an
attribute binding (`HostBinding('attr.href')`). The effect of this
change is that `DebugElement.properties['href']` will now return the
`href` value returned by the native element which will be the full URL
rather than the internal value of the `RouterLink` `href` property.

Specifically: narrow the type used for form statuses from string to a union of possible statuses. Change the API methods from any to use the new type.
This is a breaking change. However, as discussed in the PR, breakage seems minimal, and google3 has been prepped to land this.
Background: we uncovered these any typings in the course of design work for typed forms. They could be fixed in a non-breaking manner by piggybacking them on top of the new typed forms generics, but it would be much cleaner to fix them separately if possible.
BREAKING CHANGE:
A new type called `FormControlStatus` has been introduced, which is a union of all possible status strings for form controls. `AbstractControl.status` has been narrowed from `string` to `FormControlStatus`, and `statusChanges` has been narrowed from `Observable<any>` to `Observable<FormControlStatus>`. Most applications should consume the new types seamlessly. Any breakage caused by this change is likely due to one of the following two problems: (1) the app is comparing `AbstractControl.status` against a string which is not a valid status; or, (2) the app is using `statusChanges` events as if they were something other than strings.
