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 should address cases when using ng-containers with ngSwitchCase / ngSwitchDefault
and migrating them safely when they are empty.

As part of this fix, I realized that child i18n blocks don't need their
own context. Instead, we can just add their params directly to the
context for their root block, and forgo the step of merging the contexts.

Fixes a bug in the sub-template index logic that caused it to reuse
indices that had already been assigned to more deeply nested templates
PR Close#53209
Structural directives inside an i18n block previously resulted in a
"list" param value (represented as "[...|...]"). This commit adds a
special case to the template pipeline to collapse the list into a single
compound value like TemplateDefinitionBuilder does.

ICU sub-messages should be recorded as belonging to the message for the
root i18n block they are part of. This ensures that they still get
emitted even if they are nested in a child template.

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.

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.

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.

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`.

When the AOT compiler creates a delegated host for a provided TypeScript CompilerHost,
it delegates functionality back to the original via a series of internal method delegations.
However, unlike other members of the CompilerHost, `jsDocParsingMode` is not a method
and cannot be delegated in this way. Attempting to call bind on the property will result
in a runtime error. Instead, `jsDocParsingMode` is now delegated via get/set accessors.
Additionally, the override of `getSourceFile` now has an updated type signature to reflect
the additional of the `jsDocParsingMode` option for the method.

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).

When blocks were initially implemented, they were represented as containers in the i18n AST. This is problematic, because block affect the structure of the message.
These changes introduce a new `BlockPlaceholder` AST node and integrate it into the i18n pipeline. With the new node blocks are represented with the `START_BLOCK_<name>` and `CLOSE_BLOCK_<name>` placeholders.

This commit adds an `error` listener to image elements and removes both
`load` and `error` listeners once the image loads or fails to load. The `load`
listener would never have been removed if the image failed to load.
PR Close#52990
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).
