This commit fixes an issue where swapping hydrated views was not possible in the new control flow repeater. The problem was caused by the fact that an internal representation of a view had no indication that hydration is completed and further detaching/attaching should work in a regular (non-hydration) mode. This commit adds a logic that resets a pointer to a dehydrated content and we use this as an indication that the view is swtiched to a regular mode.
Resolves#53163.

Prior to this fix, the expectation that anytime then was used, else would always be present. That is not a valid assumption.

i18n template removal expected no other attributes to be present, but if a bound ngIf is present with aliases and i18n, that is more than what was expected. Now it should safely remove them appropriately.

This commit fixes an issue with hydration, which happens when a content is projected in a certain way, leaving host elements non-projected, but the child content projected.
The fix is to detect such situations and add extra annotations to help runtime logic locate those elements at the right locations.

The regexp for then and else did not ignore alphanumeric characters prior to the then and else. So if a string contained then, for example Authentication, it would incorrectly match as a then clause.

This commit updates the logic to handle hydration of multiple nodes projected in a single slot. Currently, in case component nodes are content-projected and their order is changed during the projection, hydration can not find the correct element. With this fix, extra annotation info would be included for such nodes and hydration logic at runtime will use it to locate the right element.

When ng-templates are removed, an extra space was being added when it was unnecessary. This resulted in malformed html if there was no space afterwards.

This commit updates the logic to preserve previous value of cached TView before applying overrides. This helps ensure that the next tests that uses the same component has correct provider info.

This addresses an issue where multiple ng-templates are present with i18n attributes. The offsets would be incorrectly accounted for when being replaced with an ng-container.

Common module removal would not happen when a component used a templateUrl due to the checks being in separate files. This change passes the removal analysis back to the original source file to safely remove CommonModule.

Currently the way we extract the pathname of a URL is by creating an anchor node, assigning the URL to its `href` and reading the `pathname`. This is inefficient and it triggers an internal security check that doesn't allow the `href` attribute to be set which ends up blocking https://github.com/angular/components/pull/28155.
These changes switch to using the browser's built-in URL parsing instead.

Related to #52928 but `updateAncestorTraversalFlagsOnAttach` is called
on view insertion and _should_ have made that work for views dirty from
signals but it wasn't updated to read the `dirty` flag when we changed
it from sharing the `RefreshView` flag.
For #52928, we've traditionally worked under the assumption that this is working
as expected. The created view is `CheckAlways`. There is a question of whether we
should automatically mark things for check when the attached view has
the `Dirty` flag and/or has the `FirstLViewPass` flag set (or other
flags that indicate it definitely needs to be prefreshed).

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 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).

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.

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.
