Content Projected nodes are not destroyed and recreated, like every other
situation. Enter and Leave animations were ephemeral and are
expected to run once, and then be cleared. This means that for content projection
cases, the animations would only ever work the first time they were shown / hid.
In order to resolve this, we move to an animation queue that re-runs the animation
functions stored in the LView. In most cases, this animation will run once on creation.
For content projection, the enter and leave animations will fire more than once. Animations
are stored on the LView, but indexed and scheduled by whichever RNode needs to be animated.
So we only run animations for an affected RNode, rather than potentially all in the LView.
This also moves the queue to afterRender, which is safer than right after template
execution in refreshView.

Fixes two issues that were preventing template literals from being recovered properly if one of the interpolated expressions is broken:
1. We weren't updating the expected brace counter when an interpolation starts which in turn was throwing off the recovery logic in `skip`.
2. When producing tokens for template literals, we were treating the closing brace as an operator whereas other places treat it as a character. Even after fixing the first issue, this was preventing the recovery logic from working correctly.
Fixes#63940.

Prevents migration of @input() properties that contain references to 'this' in their initializer functions. This ensures that functions accessing class members via 'this' remain unchanged, preventing potential build errors.

The event listeners for animationstart and animationend weren't properly checking whether the animation event fired matched the node we're bound to, since animation events bubble. This resulted in child node animation events bubbling up and causing elements to get prematurely removed.

angular#62630 made it so that all ARIA
property bindings would write to their corresponding attribute instead.
The primary motivation for this change was to ensure that ARIA
attributes were always rendered correctly on the server, where the
emulated DOM may not correctly reflect ARIA properties as attributes.
Furthermore, this change added support for binding to ARIA attributes
using the property binding syntax (e.g. `[aria-label]`).
Unfortunately, angular#62630 relied on
the incorrect assumptions that an ARIA property name could be converted
to its attribute name (without hardcoding the conversion), and that the
value of an ARIA property matched its corresponding attribute. For
example, the `ariaLabelledByElements` property's value is an array of
DOM elements, while the corresponding `aria-labelledby` attribute's
value is a string containing the IDs of the DOM elements.
This partially reverts angular#62630 so
that only property bindings with ARIA attribute names (begin with
`aria-`) are converted to attribute bindings.
* `[ariaLabel]` will revert to binding to the `ariaLabel` property.
* `[aria-label]` will continue binding to the `aria-label` attribute.
Note the only difference between `[aria-label]` and `[attr.aria-label]`
is that the former will attempt to bind to inputs of the same name while
the latter will not.

The control flow migration was incorrectly removing `ng-template` elements in scenarios where they were referenced by multiple `*ngIf` directives' `else` clauses and also used independently via `ngTemplateOutlet`.

When `noUncheckedIndexedAccess` is not enabled, indexed accesses do not include `undefined` in the type.
This makes the OptionalChainNotNullableCheck inconvenient when wanting to safe guard an indexed access (and when the typings isn't helping you).
Ideally project should enable `noUncheckedIndexedAccess` for better typesafety, but this is often inconveninent (we do not enable it by default) and often not the resort of the developer.
So more better coding convinience, `OptionalChainNotNullableCheck` will not raise an error/warning on indexed Acessed followed by an optional chaining when `noUncheckedIndexedAccess` is not enabled.

This commit changes `Resource.hasValue()` and its derived types to improve narrowing
of resources whose generic type either does not include `undefined` (i.e. when a default
value has been provided) or when the generic type is `unknown`. This fixes the undesirable
behavior where `hasValue()` would cause the `else` branch of an `hasValue()` conditional
to have a narrowed type of `never`, given that the `hasValue()`'s type guard covers the
entire type range already (meaning that the type in the else-branch cannot be inhabited
in the type system, yielding the `never` type).
By making the `hasValue()` method only a type guard when the generic type includes `undefined`
these problems are avoided.

This adds an optional flag to the renderer on `removeChild` called `requireSynchronousElementRemoval`, which can tell any downstream renderer that elements need to be removed synchronously. This gets passed down to the legacy animation renderer to ensure that any elements that set this flag aren't impacted by that renderers changes to timing.

Currently if `TestBed.overrideComponent` is used on a class that uses initializer APIs (e.g. `input()`), the initializer metadata will be wiped out, because `overrideComponent` re-compiles the class with the information set by `setClassMetadata`. `setClassMetadata` only captures decorated members at the moment.
These changes introduce some logic to capture the new initializer-based APIs in `setClassMetadata` as well.
Fixes#57944.

Reworks the logic that tracks the decorator metadata for members to do so using the output AST, rather than wrapping the TypeScript AST. This makes it easier to programmatically generate new members that weren't part of the TypeScript AST before.

Prior to this change the template type-check generator would incorrectly apply inputs
and attributes to a structural directive, where only the bindings as present in microsyntax
are actually bound to the directive. This introduced a problem where usages of template
variables could not be resolved, because the template variables are out-of-scope of the
template element itself.

Non-typed `transform` functions were stripped by the migration prior to this commit (while still logging an error).
This behavior will now only happen with `--best-effort`.

In production builds, `ngDevMode` is replaced with `false`, so the guard compiles to `return;`. However, bundlers like ESBuild still keep the remaining statements after the return as unreachable code instead of removing them. This leaves behind unnecessary dead code in the output.
Technically, the body is unreachable. But to prove that, the bundler must be 100% certain that:
- `return` cannot be removed by some transform
- there's no later transformation that changes control flow
As thus, it's always conservative.
This also allows dropping `assertDefined`, which was previously
referenced only inside `prependTokenToDependencyPath`. With the
function now fully inlined and dev-only, `assertDefined` is also
eliminated from production builds, further reducing bundle size.

The `checkNoChanges` method previously used an early-return guard:
if (!ngDevMode) return;
// dev-only code ...
In production builds, `ngDevMode` is replaced with `false`, so the
guard compiles to `return;`. However, bundlers like ESBuild
still keep the remaining statements after the return as unreachable
code instead of removing them. This leaves behind unnecessary dead
code in the output.
This commit updates the method to instead wrap the full body:
if (ngDevMode) {
// dev-only code ...
}
With this change, the method collapses to an empty function in
production builds:
checkNoChanges() {}
This ensures that the dev-only logic and its dependencies
(e.g. `checkNoChangesInternal`, `UseExhaustiveCheckNoChanges`) can be
fully tree-shaken, reducing bundle size.
