This commit improves the API documentation for `input` after
we added support for initializer APIs in angular.dev docs generation.
Changes:
- Rename `ReadT` to `T`. This conceptually makes it easy to talk about
inputs of type `T` if there is no transform involved. The common case.
- Rename `WriteT` to `TransformT`. This makes it clear that this is the
type that the "transform" needs to handle.
- Improves the "overall" description of the input function so that it
can be shown as a general overview for the API site.
- Improves usage notes to be a little more helpful, yielding more useful
content in the API docs usage notes section.
- Add short JSDoc description for each individual overload.

This commit adds support for extracting initializer API functions.
Initialixer API functions are functions conceptually that can are
intended to be used as class member initializers.
Angular started introducing a few of these for the new signal
APIs, like `input`, `model` or signal-based queries.
These APIs are currently confusingly represented in the API docs because
the API extraction:
- does not properly account for call signatures of interfaces
- does not expose information about sub-property objects and call
signatures (e.g. `input.required`)
- the docs rendering syntax highlighting is too bloated and confusing
with all types being included.
This commit adds support for initializer API functions, namely two
variants:
- interface-based initializer APIs. e.g. `export const input:
InputFunction`- which is a pattern for `input` and `input.required`.
- function-based simpler initializer APIs with overloads. e.g.
`contentChildren` has many signatures but doesn't need to be an
interface as there are no sub-property call signatures.

When creating the Angular Language Service instance, attempts to read
configuration files are now only attempted if the project is considered
a `Configured` project. Such a project has been analyzed by TypeScript
and one or more configuration files (tsconfig/jsconfig) files have been
found for the project.

Based on some internal feedback, these changes add validations to prevent cases where the `@for` loop variable name is the same as one of the built-in context variables, or when one of the context variables is aliased to the same name as the item.

Builds on top of the previous changes to add support for deferred blocks during partial compilation. To do this, the following changes had to be made:
* The metadata passed into `ɵɵngDeclareComponent` has an additional field called `deferBlockDependencies` which has an array of the dependency loading functions for each defer block in the template. During linking, the dependency functions are loaded by matching their template index to the index in the `deferBlockDependencies` array.
* There's a new `ɵɵngDeclareClassMetadataAsync` function that is created for components that have deferred dependencies. It gets transpiled to `setClassMetadataAsync` and works in the same way by capturing a dependency loading function and setting the metadata after the dependencies are resolved. It also has some extra fields for capturing the version which are standard in linker-generated code.
* Deferred import statements are now stripped in partial compilation mode, similar to full compilation.

Adds the `ɵɵngDeclareClassMetadataAsync` function that will be produced during partial compilation for component classes that have deferred dependencies. At runtime the dependencies will be resolved before setting the metadata.

Updates the type of the resolver function to be any `Expression` since JIT may receive a function reference rather than a `ArrowFunctionExpr`.

Switches to tracking the deferred blocks in a flat array in the binder to ensure that their template order is maintained. This will be relevant in the next commits where we'll match deferred blocks by their index.
Note that the current map we have technically guarantees the insertion order in the spec, but the array is a bit more explicit.

Updates the logic that detects if a node should be checked for control flow content projection to exit as soon as it detects a second root node, instead of counting the total and then checking if it's more than one.
PR Close#54921
Previously only the first branch of an `if` block was captured for content projection. This was done because of some planned refactors in the future. Since we've decided not to apply those refactors to conditionals, these changes update the compiler to capture each branch individually for content projection purposes.
PR Close#54921
This commit changes the way we use containers to insert conditional content.
Previously if and switch conditional would always use the first content as the
insertion container. This strategy interfered with content projection that
projects entire containers - as the consequence content for _all_ cases would
end up in slot matched by the first container. This could be very surprising
as desicribed in https://github.com/angular/angular/issues/54840
After the change each conditional content is projected into its own container.
This means that content projection can match more than one container and
result in correct display.

Currently when aliasing a `for` loop variable with `let`, we replace the variable's old name with the new one. Since users have found this to be confusing, these changes switch to a model where the variable is available both under the original name and the new one.

Previously we assumed that if a `for` loop tracking function is in the form of `someMethod($index, $item)`, it will be pure so we didn't pass the parameter to bind the context to it. This appears to be risky, because we don't know if the method is trying to access `this`.
These changes play it safe by always binding method-based tracking functions.
Fixes#53628.

This commit adds `declare` to each interface in the `zone-impl` to
prevent renaming of any interface properties by compiler optimizations.
This would otherwise cause issues if multiple applications depend on ZoneJS and
compile the interface properties to different names.

This commit refactors the router module to enhance performance by substituting the startsWith method with direct access `[0]` when verifying the value of a single character. This optimization improves efficiency, as direct access retrieves the character's value stored at a specific index in the string, resulting in slightly faster execution.

This change updates the approach to the loop in `ApplicationRef.tick`
for allowing state updates in `afterRender` hooks. It is valid to update
state in render hooks and we need to ensure we refresh views that may be
marked for check in these hooks (this can happen simply as a result of
focusing an element). This change ensures that the behavior of `markForCheck`
with respect to this loop does not change while we are actively running
change detection on a view tree.
This approach also has the benefit of preventing a regression for #18917,
where updating state in animation listeners can cause `ExpressionChanged...Error`
This should be allowed - there is nothing wrong with respect to unidirectional
data flow in this case.
There may be other cases in the future where it is valid to update
state. Rather than wrapping the render hooks and the animation flushing
in something which flips a global state flag, the idea here is that
`markForCheck` is safe and valid in all cases whenever change detection
is not actively running.

In some cases the hydration mismatch is nested within a component.
As the devTool only reports issues on the component level, we need to mark the component node rather than the actual mismatched node.

This commit updates the name of an internal function argument that represents an embedded view injector. Also it introduces a new config option that allows passing an environment injector to be used in the underlying LView.

BREAKING CHANGE:
Legacy handling or Node.js URL parsing has been removed from `ServerPlatformLocation`.
The main differences are;
- `pathname` is always suffixed with a `/`.
- `port` is empty when `http:` protocol and port in url is `80`
- `port` is empty when `https:` protocol and port in url is `443`
