I previously strengthened some weak types in #44370. One of these fixes exposed an incorrect call into `_reduceChildren` from `_reduceValue`. This was caught in google3 by a caller who was extending `FormGroup` and overriding these methods.
Special thanks to Bart G for catching this issue and suggesting a fix.

Allow a FormControl to be reset to its initial value. Provide this feature via a new option in a FormControlOptions interface, based on AbstractControlOptions.
Also, expose the default value as part of the public API. This is part of a feature that has been requested elsewhere (e.g. in #19747).
This was originally proposed as part of typed forms. As discussed in the GDE session (and after with akushnir/alxhub), it is likely better to just reuse the initial value rather than accepting an additional default.
It is desirable to land this separately in order to reduce the scope of the typed forms PR, and make it a types-only change.
Pertains to issue #13721.

It is possible to pass arguments to `FormBuilder` using four different formats: value-only, boxed value, control config, and value-array. Currently, these different methods are not well-tested, especially as they interact. This PR will add tests for the variety of different argument shapes.
This was originally inspired by typed forms: when `FormBuilder` becomes typed, all these argument shapes should just work, with correct inferred types.

Currently, many of our unit tests are written to use heterogenous groups and arrays, and controls that accept heterogenous values. This PR will make the minimum possible alterations to prepare those usages, mainly by annotating them as untyped controls, etc.
This PR is *not* intended to test typed forms, merely to minimize the size of the upcoming PR. This will allow that PR to be focused on the actual features and tests, rather than boilerplate fixes.

Now that ViewEngine libraries can no longer be created, the latest
TypeScript version that ngcc should be able to process is TypeScript 4.3,
i.e. the version of TypeScript that was supported in Angular 12.
However, ngcc's integration tests used the TypeScript version of the
workspace to create the JavaScript files from TypeScript sources on
demand. This introduces friction when upgrading the TypeScript version
within the workspace, as changes to TypeScript's emit format may affect
ngcc's ability to process it correctly.
The on demand creation of JavaScript files was convenient for authoring
tests, but it also helped to detect incompatibilities with newer
versions of TypeScript. Now that ngcc no longer has to process newer
versions of TypeScript, we want to pin the integration suite to use
JavaScript code as if it were compiled using TypeScript 4.3, i.e. a
version of TypeScript that is actually supported by ngcc.
This commit updates the integration test to inline all the generated
files directly in the tests, instead of compiling them on demand. This
was done by temporarily installing TypeScript 4.3 and using it to create
the `loadTestFiles` statement from the original TypeScript inputs.
An alternative could have been to install TypeScript 4.3 as an actual
dependency in the workspace and using that to continue compiling the
integration suite on demand, but this brings some overhead in package
installations (TypeScript is ~60MB) and the authoring aspect of ngcc
integration test is expected to diminish, now that ngcc's support is no
longer a moving target.

* 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`.

Previously, when processing UMD, ngcc assumed that the `exports`
argument of the CommonJS factory call (if present) would be the first
argument of the call. This is generally true for the supported UMD
formats, but can change if ngcc prepends more imports (and thus factory
arguments) while processing the module. This could lead to errors when
trying to collect dependencies of an already processed module.
(This was accidentally broken in #44245 (commit 2bc3522e16).)
This commit fixes it by not making any assumptions about the position of
an `exports` argument in the CommonJS factory call.

This commit makes several changes to the implementation of `NgForOf` to
reduce its code size in production builds:
1. The tailor-made message for an unsupported differ is fully
tree-shaken in production builds, in favor of the exception from the
differ factory itself.
2. The private `_perViewChange` method was changed into a free-standing
function, to allow its name to be minimized.
3. The need for an intermediate `RecordViewTuple` was avoided by
applying the operation in-place, instead of collecting all insertions
into a buffer first. This is safe as the `_perViewChange` operation
that used to be done on each `RecordViewTuple` is entirely local to
the tuple itself. Hence, it is invariant to execution ordering which
means that the `_perViewChange` can be executed directly during the
`forEachOperation` loop.

The downlevel decorator transform (commonly used in the CLI and other
tooling of the ecosystem for enabling JIT ES2015+), is currently
incorrectly dealing with nested classes.
The transform will accidentally visit nested classes (in a constructor)
multiple times and generate duplicated instances of the `ctorParameters`
fields. This does not sound like an issue at first, but the duplicated
`ctorParameters` fields will miss significant type information that has
been elided by the first visit, resulting in generated code like the
following:
```js
let MyClass = /* @__PURE__ */ __name(class MyClass extends UpgradeNg1ComponentAdapter {
constructor(scope, injector3, elementRef) {
}
}, "MyClass");
MyClass.ctorParameters = () => [
{ type: void 0, decorators: [{ type: Inject, args: [$SCOPE] }] },
{ type: Injector },
{ type: ElementRef }
];
MyClass.ctorParameters = () => [
{ type: void 0 }, // <---- NOTE!
{ type: Injector },
{ type: ElementRef }
];

Fixes an issue where destroy hooks are not set up for `useClass` providers
that rely on `forwardRef` for passing the actual class reference.
Currently the destroy hooks are not captured because forward refs are
not resolved for class providers. In ES2015+ this issue becomes even
more critical if arrow-functions are used for
e.g. `useClass: () => forwardRef(..)`.
This is because arrow functions do not have a prototype, unlike in ES5
where the function assigned to `useClass` would always have a prototype.
In ES2015+ a runtime exception as followed is returned (and doesn't give
any useful indication of the forwardRef issue):

Bundle spec files similar to how it is done within the Angular
Components repo. This should simplify the setup and also speed
up the Saucelab job as only a single spec bundle would need to be
downloaded, compared to having to load hundreds of files through the
Saucelabs tunnel.
Also makes a couple of tests more robust with the emulators/and accounts
for ES2015 test runner changes. The tests should be less reluctant to
such build process changes.
Note for reviewers: Some imports have been simplified here. This work
came from Joey's original WIP for this. It's unclear to me whether this
is still needed, but it sounded like this was necessary for the ESBuild
bundling to work. I have robusted the module resolution plugin though,
so I doubt it's still needed. At the same time though: Not worth
reverting/trying as these changes are nice to have anyway!

When we are going to the definition of an input, we find _both_ the
definition of the input _and_ also look for any directives which have
a selector that matches the input. For example:
```
@Directive({
selector: '[greeting]'
})
export class MyDir {
@Input() greeting!: string;
}
```
With this commit, we now correctly handle the case where inputs and/or
selectors have a dollar sign in them. The dollar sign has special
meaning in CSS, but when we encounter the dollar in a template, we need
to escape it when used as a selector so that it is taken as a dollar
literal rather than a character with special meaning.
Previously, we were not escaping the dollar sign and the CSS parsing
logic would throw an error. The change in this commit prevents that
error from happening, but a `try...catch` is still added in case there
is another unhandled use-case. If this happens, we do not want the
`goToDefinition` operation to completely fail.

Previously, the mock packages created for `UmdDependencyHost`'s tests,
specified the entry-point as `esm2015`. This does not matter in tests,
since the packages are explicitly passed to the `UmdDependencyHost`
(while in reality the appropriate host would be determined based on the
name of the entry-point property - in this case, detecting the
entry-point as ES2015 and not UMD).
However, in order to avoid confusion, this commit updates the test
packages to use `main` (the default property used for the UMD format in
`package.json` files).

Previously, the ngcc `UmdReflectionHost` would throw a misleading error
when trying to collect dependencies of an invalidly formatted UMD
module. This happened because an error would be thrown while trying to
