This commit fixes an issue that happens when an i18n block is defined as a projectable content, but a parent component doesn't project it. With an extra check added in this commit, the code will be taking a regular "creation" pass instead of attempting hydration.
Resolves#57301.

This commit updates serialization and hydration i18n logic to take into account situations when i18n blocks are located within "skip hydration" blocks.

Previously, if a component injects a `ViewContainerRef`, the post-hydration cleanup process doesn't visit inner views to cleanup dehydrated views in nested LContainers. This commit updates the logic to recognize this situation and enter host LView to complete cleanup.

These changes replace most usages of `removeChild` with `remove`. The latter has the advantage of not having to look up the `parentNode` and ensure that the child being removed actually belongs to the specific parent.
The refactor should be fairly safe since all the browsers we cover support `remove`. [Something similar was done in Components](https://github.com/angular/components/pull/23592) some time ago and there haven't been any bug reports as a result.

Lock file maintenance updated Terser, which impacts the bundle
optimizations being tested via the symbol golden tests.
There was a small noticable change in the symbol golden where
`withDomHydration` is now preserved, and the underlying function
that was previously detected is gone. Seemingly Terser now inlines
this function and had to preserve `withDomHydration` as the entry point.

Rather than leaving the timers around as no-ops, this commit updates the
logic to also attempt to clear or cancel the timers. This is helpful for
the eventual goal of running the scheduler in the `fakeAsync` zone (if
the test is running in `fakeAsync`) rather than scheduling in the root
zone and making it impossible to flush.

This creates a private option that can be used internally while we
migrate this to the default and only behavior. ~200 tests in TGP have errors
that are being swallowed (console.log) and not causing the test to fail.
We can first explicitly opt those out, flip the default internally, then
"fix" them by adding expect...toThrow.

To increase the ease of development we are moving @angular/docs into the adev directory within this repo. While
we are doing this to improve our development experience in the short term, efforts are also in place
to maintain a division between this @angular/docs (shared) code and adev itself, so that it can be extracted
back out in the future when components is ready to leverage it as well.

The behavior of `ComponentFixture` for zoneless tests was decided somewhat through guesswork, trial, and error. In addition, working on the zoneless fixture revealed oddities in the behavior of the zone-based fixture, or behaviors that we felt were counterintuitive. The most consequential difference is how change detection works: `detectChanges` goes through ApplicationRef.tick in zoneless while it is `changeDetectorRef.detectChanges` in the zone fixture.
We felt that running change detection through `ApplicationRef.tick` was important for several reasons:
* Aligning application behavior more closely with the test behavior (almost all views are attached to application ref in reality)
* Ensuring that afterRender* hooks are executed when calling `fixture.detectChanges`
* Ensuring that the change detection runs again if render hooks update state
This change, however, has some noticeable consequences that will break some tests, mostly around how errors are handled. `ApplicationRef.tick` catches errors that happen during change detection and reports them to the ErrorHandler from DI. The default error handler only logs the error to the console. This will break tests which have `expect(() => fixture.detectChanges()).toThrow()`. In addition, it allows tests to pass when there are real errors encountered during change detection.
This change ensures that errors from `ApplicationRef.tick` are rethrown
and will fail the test. We should also do a follow-up investigation to
determine whether we can/should also do this for the zone-based
`ComponentFixture`.

Fixes that the runtime implementation of `ɵɵngDeclareDirective` was interpreting the `hostDirectives` mapping incorrectly. Instead of treating the inputs/outputs as `['binding', 'alias']` arrays, it was parsing them as `['binding: alias']`. This was leading to runtime errors if a user is consuming a partially-compiled library in JIT mode.

This is the first step towards combining `EarlyEventContract` and `EventContract`. It contains a few refactors, such as making names more consistent.
The goal of this refactor is to remove the `EarlyEventContract` class altogether, as well as `EventContract`.
To install the early event contract with the default events in early script tag, users will call:
`bootstrapGlobalEarlyEventContract()`
And for boostraping:
`registerGlobalDispatcher(dispatcher)`

Currently the logic that maps a name to a variable looks at the variables in their definition order. This means that `@let` declarations from parent views will always come before local ones, because the local ones are declared inline whereas the parent ones are hoisted to the top of the function.
These changes resolve the issue by giving precedence to the local variables.

Now that all `Dispatcher` implementations use `ActionResolver`, `EventContract` no longer needs to. Additionally, all a11y click support has been removed. `EventContract` will not specifically listen for `keydown` automatically, as all `EventContract` instances already have `keydown` listeners. This removes the need for the `A11Y_CLICK_SUPPORT` define, which will be removed in a future PR.

Enables the new `@let` syntax by default.
`@let` declarations are defined as:
1. The `@let` keyword.
2. Followed by one or more whitespaces.
3. Followed by a valid JavaScript name and zero or more whitespaces.
4. Followed by the `=` symbol and zero or more whitespaces.
5. Followed by an Angular expression which can be multi-line.
6. Terminated by the `;` symbol.
Example usage:
```
@let user = user$ | async;
@let greeting = user ? 'Hello, ' + user.name : 'Loading';
<h1>{{greeting}}</h1>
```

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.
