Currently we produce the string value of a defer `on` trigger by concatenating the string values of all of its tokens. This ends up ignoring whitespaces which in turn throws off source spans.
These changes switch to producing the string by taking the text between the start and end tokens, as well as tracking the start index.

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).

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.

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.

This updates the enter and leave logic to use the stored LView data to dispatch the enter and leave animations at the right points in the lifecycle. This should fix issues with signals not being available yet, parallel animations, and also eliminate the need for the element registry.

The new animations was not correctly looking for the `.` when parsing bindings. This resulted in arbitrary event bindings creating animate.leave instruction calls.

The animate instructions were getting applied to the container comment nodes as well as the element nodes. This prevents that on the compiler level.

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)

Similar fix as #63082, but for template attributes. The root cause is the same where we should be using `fullStart` instead of `start` in order to account for whitespaces being skipped.
Fixes#63157.

When parsing expressions inside a bound attribute, we offset all of its spans by an `absoluteOffset` in order to get the right spans in the source file. The offset was incorrect when parsing an attribute with leading spaces during the construction of the Ivy AST, because of the combination of:
1. We were setting the offset by looking at `valueSpan.start`.
2. The Ivy parser sets `leadingTriviaChars: [' ', '\n']` which means that spaces and new lines will be ignored in the `sourceSpan.start`.
These changes resolve the issue by using `valueSpan.fullStart` which includes the leading spaces.
Fixes#63069.

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.

When we introduced blocks, we made a deliberate decision to treat the `@` character as a reserved character in case we need to use it for other syntax in the future. This meant that some common cases, like writing out an email address in the template, can be broken.
After some recent discussions we decided to relax the requirement and only treat `@` as a reserve character if it's followed by a character sequence that matches a known block.
