Based on recent discussions, these changes remove the Windows CI check because it has been too flaky for too long. Furthermore, we've concluded that the simulated file system in the compiler tests already catches the same set of bugs as running the tests on a real Windows system.

Using `afterRender` schedules long-living lifecycle hooks. Scheduling
such hooks inside reactive contexts could mean that many of the
same hooks would be scheduled, quickly piling up every time a
consumed signal changes. This is likely unintended and could degrade
application performance or result in unexpected behavior.
Additionally, scheduling `afterRender` inside a `computed` is considered
a side effect. Computed expressions are expected to be pure/ i.e. free
of side effects. We can avoid this caveat by detecting the reactive
context in development.

Using an `effect` inside a `computed` is a clear violation of
the conceptual idea of computed's being pure/ side-effect free.
Additionally, scheduling new effects from an existing actively
running effect is likely unintended as this could degrage application
performance or result in unintentional behaviors. Multiple long-living
effects would be scheduled every time the effect expressions runs.
For these reasons, we are explicitly preventing this pitfal, by
disallowing using `effect` inside reactive contexts.

This commit introduces 2 new features into DevTools.
Directive level dependency inspection: Users can now view which dependencies their directives have injected in the property viewer tab. This view displays not only the dependency but also the resolution path that was used to service the injection.
Injector graph inspection: Users can now view a visualization of the element and environment hierarchies in their application. These trees are displayed separately but on the same page in the Injector Tree tab. User can click on individual injectors to view a list of all the providers configured in that injector, as well as highlight the resolution path from that injector to the root (with the corresponding environment injector connection highlighted as well).

Previously getDependenciesForTokenInInjector was unable to determine which node on a view serviced a specific injection. Now it is able to filter out those injections that did not come from the specific node for the NodeInjector passed into it.
Previously getInjectorMetadata was incorrectly looking up DOM elements for some directives (for example NgForOf) where an LContainer was created. Now the LContainer case is handled, and the non LContainer case uses `getFirstNativeNode` to more accurately get the element we want.

This commit adds support for extracting type alises. It currently
extracts the raw written type from the source without performing any
resolution, such as for resolving `typeof` queries, as current Angular
public APIs do not rely on this.

Updates the Ivy AST to allow for `@switch` blocks to capture nested blocks that are not `@case` and `@default`. These blocks will be used for autocompletion in the language service.
These changes also update the logic for `@switch` and `@if` blocks so that they produce an AST node even if there are errors. The errors will still be surfaced to users, but producing AST nodes allows us to recover parts of the expression later if necessary.

This commit adds the ability to provide a function that will get called
immediately after the view transition is created. This will allow
developers to do things like add/remove classes from the DOM when the
transition animation is finished, skip the transition based on
application conditions, etc. Having access to the transition unlocks
just about every example outlined in https://developer.chrome.com/docs/web-platform/view-transitions.
Note that the timing of the `updateCallback` execution is in the spec as
being called asyncronously (https://drafts.csswg.org/css-view-transitions-1/#callbackdef-updatecallback).
This means the `onViewTransitionCreated` callback is guaranteed to
execute before the update callback which in turn means it is guaranteed
to execute before the view transition `ready`/animation. As a result, it
is safe/effictive to add classes to the document in the
`onViewTransitionCreated` function in order to control animations of
that transition and then remove those classes in the transition's `finished`
`Promise`. The animation also doesn't start until the `Promise` returned
by `updateCallback` resolves, so this would also guarantee that the
animation starts asynchronously.

Adds a check to the viewport cleanup function to prevent it from re-processing elements that have been fully cleaned up, because it can lead to the `IntersectionObserver` being destroyed even though there are still pending triggers. This can happen, because we have cleanup callbacks both for the block is loaded, but also when the placeholder view is destroyed.
Fixes#52113.

Fixes that the new block syntax was generating instructions in the wrong order which meant that pipes were being declared too early. This meant that if the block is first in the template, any pipes used in it won't be able to inject things like `ChangeDetectorRef`.
These changes update the compiler and add a bunch of tests to ensure that pipes work as expected.

When a route has loadComponent, its children should not inherit params and
data unless paramsInheritanceStrategy is 'always'.

BREAKING CHANGE: Routes with `loadComponent` would incorrectly cause
child routes to inherit their data by default. The default
`paramsInheritanceStrategy` is `emptyOnly`. If parent data should be
inherited in child routes, this should be manually set to `always`.

This commit updates `@defer` logic related to handling `after` and `minimum` parameters tree-shakable.
If `after` or `minimum` was used on a `@loading` or `@placeholder` blocks, compiler generates an extra argument for the `ɵɵdefer` instruction. This extra argument is a reference to a function that brings timer-related code.

The current error stringifier only includes the class name. In this change a new stringifier is added which returns a more helpful string which includes the file path and line number. Note that this is only the case with components, and for other class types (directive, pipes) it will fallback to the current stringifier. Subsequent changes can cover the case of directive and pipes as well.

A new statement will be generated for components which will attach some useful debug info to them to be used in runtime error handling. Currently this only happens in full and local compilation modes.
PR Close#51919
A new utility function `compileClassDebugInfo` is introduced which creates compile result necessary to generate statement for attaching some useful debug info into angular classes. An example of teh new statement would be:
```
(() => { (typeof ngDevMode === "undefined" || ngDevMode) && i0.ɵsetClassDebugInfo(Main, { className: "Main", filePath: "$PROJECT_ROOT/src/main.ts", lineNumber: 8 }); })();
```
Currently, the debug info contains:
- the class name
- the file path in which it is defined
- the line number in which it is defined
The debug info will be used in runtime to generate more helpful error messages.

This commit updates the tracking of dirty child views to be a flag
rather than a counter. This is a much more simple method and less likely
to get into the same 'always-wrong' situation that could happen with the
counter (if it is off by 1 once, it's off by 1 forever and you either
get infinite change detection or your view is never refreshed).
