This commit updates the implementation of the `ImagePerformanceWarning` and
runs the image scan even if the page has already been loaded. The `window.load`
event would never fire if the page has already been loaded; that's why we're
checking for the document's ready state.

This separates out the NgSwitch migration pass from the NgSwitchCase / Default pass, which makes nested switch migrations work.

With if then else use cases, we now properly account for the length

Currently in the angular.dev documentation, afterNextRender function
take directly the phase as a second parameter which is not correct.
According to the api of this hook, the second parameter is an object
which contains the phase. This PR update the part of the documentation
PR Close#53025
This commit cleans up the `loadingPromise` when no `dependenciesFn` is defined,
as it's already cleaned up after the resolution of `Promise.allSettled`. This
occurs with `prefetch on` triggers, such as when `triggerResourceLoading` is called
from `ɵɵdeferPrefetchOnImmediate`, where there are no dependencies to load. The
`loadingPromise` should still be cleaned up because it typically involves the
`ZoneAwarePromise`, which isn't properly garbage collected when referenced elsewhere
(in this case, it would be referenced from the `tView` data).

This is a follow-up to the fix from #52414. It adds a diagnostic that will tell users when a control flow is preventing its direct descendants from being projected into a specific component slot.
PR Close#52726
The control flow projection diagnostic will mention `ng-container` as a workaround for projection multiple nodes. These changes add a couple of tests to ensure that the approach works.
PR Close#52726
These changes expose the `ngContentSelectors` and `preserveWhitespaces` metadata to the TCB so they can be used in the next commit to implement a new diagnostic.

When doing directive matching in the compiler, we need to be able to create a selector from an AST node. We already have the utility, but these changes simplify the public API and expose it so it can be used in `compiler-cli`.

This commit removes the `load` event listener once it has fired within the
`ImagePerformanceWarning`. The `load` event listener prevents the zone stuff from
being garbage collected in development mode when debugging microfrontend applications
that may be destroyed multiple times.
PR Close#52512
The `$first`, `$last`, `$even` and `$odd` variables in `@for` loops aren't defined on the template context of the loop, but are computed based on `$index` and `$count` (e.g. `$first` is defined as `$index === 0`). We do this calculation by looking up `$index` and `$count` when one of the variables is used.
The problem is that all `@for` loop variables are available implicitly which means that when a nested loop tries to rewrite a reference to an outer loop computed variable, it finds its own `$index` and `$count` first and it doesn't look up the ones on the parent at all. This means that the calculated values will be incorrect at runtime.
These changes work around the issue by defining nested-level-specific variable names that can be used for lookups (e.g. `$index` at level `2` will also be available as `ɵ$index_2`). This isn't the most elegant solution, however the `TemplatDefitinionBuilder` wasn't set up to handle shadowed variables like this and it doesn't make sense to refactor it given the upcoming template pipeline.
Fixes#52917.

Reworks the `repeater` instruction to go through `advance`, instead of passing in the index directly. This ensures that lifecycle hooks run at the right time and that we don't throw "changed after checked" errors when we shouldn't be.
Fixes#52885.
PR Close#52935
Currently, when a component is overriden using `TestBed.overrideComponent`, Angular retains calculated scope for that component (a set of components and directives used within a component). This may cause stale information to be used in tests in some cases. This commit updates the logic to reset overridden component scope, so it gets re-computed during the next invocation.
Resolves#52817.

The call signature of detectChangesInternal requires parameters that can all be
found directly on lView. This commit removes those paramters and instead
grabs them in the function implementation.

These tests ensure signals can be read in a template after embedded
views are created in the middle of template execution of an update pass.
The embedded view templates are executed in create mode in the middle of
the component template being executed in update mode. This behavior was
found to not work correctly in past implementations of the reactive
template consumers.
