It is valid CSS to list keyframe names in an animation declaration only
separating the names with a comma and no whitespace. This is typical of
production builds. Updated a couple of regexes and added a couple of
tests to account for this scenario.

In this update, the fetch backend now executes fetch operations outside of the Angular zone. This adjustment primarily aims to decrease Continuous Delivery (CD) cycles on Node.js. The decision was influenced by Undici, the Node.js fetch implementation, which relies on `setTimeouts` to manage response timeouts.

This commit updates the logic that create an injector for defer blocks (when it's needed) to account for a situation when a component is instantiated without a connection to the current component tree. This can happen if a component is created using its factory function or via `createComponent()` call.

This change is the final cleanup after removing NgSwitch's equality patch
that was used in G3 to allow == matching for a certain period of time. This
code is no longer needed as both the external ecosystem and G3 are using
=== equality for matching NgSwitch cases.

This should make things somewhat faster, since setAttribute can be slower than addEventListener. Jsaction attribute is still needed for SSR though.

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.

When running the JIT transforms in 1P w/ tsickle, tsickle will
transform source files before our custom transforms can run. This is
also impacting the Ivy transform and hence we use `ts.getOriginalNode`
in various places to inspect the source AST for detecting Angular.
For the JIT transform we need to do a similar change so that the
transform could run in 1P.

In Angular v17 we've alligned NgSwitch equality check with the build in control
flow to be ===. At the same time we've left the ability to use ==. This ability was
controlled by the NG_SWITCH_USE_STRICT_EQUALS const targetted by the G3 patch.

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.

This commit delays makes two changes:
* Use the `read` phase for `afterNextRender` hook. We really want to
wait for any write hooks to complete before starting the animation
* In addition, wait a macrotask before resolve (really, this makes the
above change unnecessary but it's still conceptually the right
thing). This ensures any follow-up rendering in the microtask queue
is flushed before the animation starts.
Important note: This only affects the timing of the animation start,
delaying it longer to allow additional rendering/change detections to
flush. This promise already resolves in an `afterNextRender` hook and is
only used directly by the browser's view transition machinery.

These changes integrate let declarations into the template pipeline. This involves a few operations:
* Producing a `declareLet` instruction call at creation time to initialize the declaration.
* Producing a `storeLet` instruction call in the place of the let declaration, including the necessary `advance` calls beforehand.
* For let declarations used within their declaration view, moving the `const` to be placed right after the `storeLet` call to ensure the their value has been computed.
* For let declarations that are _only_ used in their declaration view, removing the `storeLet` call and inlining the expression into the constant statement.

`DOCUMENT` instances retrieved from DI may not contain a necessary function to complete the cleanup. In tests that don't interact with DOM, the `DOCUMENT` might be mocked and some functions might be missing. For such tests, DOM cleanup is not required and we can skip DOM cleanup logic if there are missing functions. For tests that use DOM, TestBed would behave the same as before and rely on more complete `DOCUMENT` instances.

Router's `OutletInjector` required a special handling in cases when `@defer` is used, see https://github.com/angular/angular/pull/55374 for additional info. As a result, the `ChainedInjector` that represents an `OutletInjector` instance is currently exposed via `getInjectorResolutionPath` function. This creates a problem, because other debug APIs used by DevTools can not interact with `ChainedInjector`s. This commit updates the logic around `getInjectorResolutionPath` utility to avoid exposing `OutletInjector`in the resolution path.

Many developers find these interfaces useful for various reasons. Beyond
that, the deprecation of the interfaces has incorrectly implied that
existing class-based guard implementations need to be migrated to
functions. Class injectables are _not_ deprecated and choosing to
implement a guard's state and logic as a class that is injectable in the
functions run inside the injection context is valid.

This allows for helpers like the following to work intuitively for all
types of "input fields". It also establishes the intended mental
philosophy that a model is both an input and an output.
```ts
/** Unwraps all signal input properties. */
export type UnwrapSignalInputs<T> = {
[K in keyof T]: T[K] extends InputSignalWithTransform<any, infer WriteT>
? WriteT
: T[K];

The linker inserts the constant statements that are needed to support compiled templates
after the import statements of an ESM file, but it failed to account for import statements
that are not at the top of the file. This is typically seen in FESM files where multiple
individual ESMs have been concatenated into a single ESM file, with imports in various places.
The linker would then find the very last import statement to insert the constant statements
after, but this may result in TDZ errors for component templates that have been emitted
earlier in the file.
This commit updates the Babel linker plugin to insert constant statements after the last
import of the first import group, therefore avoiding the TDZ error.

The import manager ensures generation of unique identifiers when
inserting imports. This is done by inspecting existing identifiers
within the original source file, while also checking if a similar
identifier was generated at an earlier time. This is correct behavior.
We can improve the detection so that the same identifier can be
generated in different files. This is beneficial for schematic/migration
use-cases where we wouldn't want to generate import aliases in multiple
files just because we generated an import to e.g. `input` previously.
E.g. it's fine to generate
```ts
// a.ts
import {input} from '@angular/core';
// b.ts
import {input} from `@angular/core';
// instead of `input as input_1`.

Whenever we parse object property assignment shorthands in expression
ASTs, the AST will have no information about whether the property read
for the `LiteralMap` is built based on the shorthand or not.
Exposing this information in the AST is useful for migrations as those
might need to decompose the shorthand into its longer form to e.g.
invoke a signal read.
