For each field state property, check if it has changed since the last
time it was checked before writing it the corresponding form control
property.
The `pattern` and `required` properties of the field state now return a
default value rather than `undefined` if not defined by metadata.
Renames the control directive and the input that users set to bind a
field to a UI control.
Previously users would do:
```
<input [control]="someField">
```
Now users will do:
```
<input [filed]="someField">
```

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.

Move most of the implementation of the `Control` directive into core
framework instructions. This allows field state changes to be propagated
to their corresponding UI controls directly during execution of a
template update block, instead of relying on `effect()`s to synchronize
each change later during the update (and too late in the case of
required inputs).
* Define a private API in `@angular/core` for signal forms to implement:
* `ɵControl` for the `Control` directive.
* `ɵFieldState` for the control's associated `FieldState`.
* Emit specialized instructions when compiling a `[control]` binding:
* `ɵɵcontrolCreate` sets up the `ɵControl` directive if present,
determines whether it's bound to a native control element or a
custom control component, and adds the appropriate event listeners
to notify the `ɵFieldState` of UI changes.
* `ɵɵcontrol` propagates changes from `ɵFieldState` properties to their
corresponding UI control properties (in additional to binding the `control`
property itself).

* Emit a `ɵɵcontrol` instruction in place of `ɵɵproperty` for property
bindings named "control". This instruction cannot be chained, but is
otherwise functionally equivalent.
* Upcoming changes will use the `ɵɵcontrol` instruction to bind a signal
form field to a UI control (be it a native element or custom directive).

This commit updates the TypeScript configuration across the project to use `moduleResolution: "bundler"`. This modernizes our module resolution strategy to align with current TypeScript best practices and bundler behaviors.
The following changes are included:
- Updated `tsconfig.json` files to set `moduleResolution` to `"bundler"`.
- Updated the `rules_angular` bazel dependency to a version compatible with these changes.
- Adjusted related test files and golden files to reflect the new module resolution strategy.

https://github.com/angular/angular/pull/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, https://github.com/angular/angular/pull/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 https://github.com/angular/angular/pull/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.

Ts 5.9 introduced a regression coming from 5.8 when parenthesis aren't generated for expressions like (`(a ?? b) && c`).
This fix works around this explicitly specifying that we want to keep those parenthesis that we're aware of in this specific case;
This change can be reverted if the root issue (https://github.com/microsoft/TypeScript/issues/61369) is fixed. (but let's keep the tests in any case for the coverage)

Currently the HTML parser will stop parsing as soon as it hits an end character in the name of an attribute (e.g. `/` or `>`). This ends up being problematic with some third-party packages like Tailwind which uses a wider range of characters for its class names. While the characters are fine when inside the `class` attribute, our current parser behavior prevents users from setting those classes conditionally through `[class.]` bindings.
These changes adjust the parser to handle such cases.
Fixes#61671.

Allow binding to ARIA attributes using property binding syntax _without_
the `attr.` prefix. For example, `[aria-label]="expr"` is now valid, and
equivalent to `[ariaLabel]="expr"`. Both examples bind to either a
matching input or the `aria-label` HTML attribute, rather than the
`ariaLabel` DOM property.
Binding ARIA properties as attributes will ensure they are rendered
correctly on the server, where the emulated DOM may not correctly
reflect ARIA properties as attributes.
Reuse the DOM schema registry from the compiler to map property names in
type check blocks.
