Caches information about the kind of form control that a `TNode`
represents in `TNodeFlags`. This avoids redundant computations on
subsequent template create and update passes.
Renames the `INVALID_CONTROL_HOST` error code to
`INVALID_FIELD_DIRECTIVE_HOST` for clarity and adds a test for it.

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).

An invalid APP_ID could be responsible to generating broken CSS selectors. (eg `:` is an example for a character that breaks a selector by being a separator for pseudo-selectors.)
We now throw an error if the provided value is not alphanumerical

Currently when loading external resources in JIT, when `fetch` fails,
the `text` is empty and the component is loading. This hides the actual
underlying fetch error. We should properly detect this and error out.

When the HMR is enabled in Angular, all `@defer` block dependencies are loaded
eagerly, instead of waiting for configured trigger conditions. From the DX perspective,
it might be seen as an issue when all dependencies are being loaded eagerly. This commit
adds a logic to produce a message into the console to provide more info for developers.

Calling `setInput` while the component already has an `inputBinding` active can lead to inconsistent state. These changes add an error that will be thrown if that's the case.

Sets up the symbols used to power the upcoming `inputBinding` functionality.
I also fixed that `setDirectiveInput` was incorrectly only allowing strings for the `value` parameter.

This commit updates the code of the incremental hydration feature to make the `DeferBlockRegistry` class tree-shakable. The class is only needed for hydration cases and it should not be included into client bundles for client-only apps.
PR Close#58424
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.

We don't have any docs yet for that error, so I'm removing the minus sign which indicate that there is a dedicated error doc.
