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.

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.

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];
};

Integrates let declarations into the template type checker by producing corresponding constants in the TCB.
This also includes a couple of custom diagnostics to flag usages of let before they're declared and illegal writes to let declarations. We can't rely on TS for these checks, because it includes the variable name in the diagnostic.

This makes events bubble! This change also contains changes to

so that we avoid odd timing issues. This can be split out though.
Lastly, we have one cleanup change to move the mapping from

Angular has long had the ability to use different interpolation delimiters
(by default `{{` and `}}`). This concept was copied over from AngularJS,
where AngularJS syntax is included in HTML sent over the network to the
browser. Occasionally developers would use SSR frameworks which _also_ have
interpolation syntaxes of their own, so there was a need to change the
delimiters used by AngularJS to avoid conflicts.
Since Angular templates are always processed by our compiler and the
interpolation characters are never processed by other systems first, this
option is vestigial in Angular and only increases the complexity of our
parser.
DEPRECATED: `@Component.interpolation` is deprecated. Use Angular's
delimiters instead.

This commit adds a feature that is useful for determining if an
application is zoneless-ready. The way this works is generally only
useful right now when zoneless is enabled. Some version of this may be useful in
the future as a general configuration option to change detection to make
`checkNoChanges` pass always exhaustive as an opt-in to address #45612.
Because this is an experimental, debug-only feature, it is okay to merge
during the RC period.

The new ExperimentalPendingTasks API lets developers to add and remove

This API is important for all the use-cases that depend on the concept

Angular is an opinionated framework, feature guidance will help developer choose the recommended way to enable feature (like Http requests here).
Note: This is not an indication of deprecation for `NgModule`. The deprecated module's only purpose here was to define providers. This can be done directly by the provide function pattern.

This commit introduces a check plus an associated warning for situations where
the combination of the collection change and the tracking expression resulted
in the entire view structure managed by @for to be re-created.
The check uses the following conditions before raising a warning:
- the entire collection was re-created and there were no other operations (ex.: move);
- views in a collection are considered "expensive" to re-create;
- a developer is using tracking by identity.
The last condition tries to capture cases where changes to immutable data
collections can cause significent performance and / or corectness problems.
Note that this warning might be "overreacting" and report cases where
the collection re-creation is the intended behavior. Still, the assumption is that
most of the time it is undesired.
