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.

There are cases where the application's default behavior is 'reload' and
a certain navigation might want to override this to be `ignore` instead.
This commit allows `onSameUrlNavigation` in the `router.navigateByUrl`
to be `ignore` where it was previously restricted to only `reload`.

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.

This should fix the issue where if the same ng-template is used with multiple if / else statements, it replaces all usages properly.

Previously we had logic for a special case where a root injector in standalone apps would skip the import paths calculation step for the `getEnvironmentInjectorProviders` function.
This commit intends to fix this for two other cases, namely:
- When an injector is created by a route (via the `providers` field and lazy loading).
- When an injector is manually created and attached to the injector tree
It does this by assuming that any environment injector it cannot find a provider imports container for was created without one, and simply returns the raw provider records without the import paths calculation.

This update removes imports from component decorators and at the top of the files. It only removes standalone imports though. It does not remove CommonModule if that is the only import.

In some cases ICU expression placeholders may have trailing spaces that
need to be trimmed when matching the placeholder to its corresponding
text binding.

We were previously counting the i18n expression index and deciding when
to apply i18n expressions based on the i18n context. These should be
done based on the i18n block instead.
PR Close#52698
The previous commit added support for interpolated text in ICUs, but it
made the assumption that the interpolation would be a single variable
read expression.
To properly support all kinds of interpolation expressions, this commit
refactors how ICUs are ingested to allow us to re-use the same logic we
use for bound text outside of ICUs.
To accomplish this, the `IcuOp` creation op has been removed in favor of
a pair of ops: `IcuStartOp` and `IcuEndOp`, that mark the beginning and
end of the ICU. Now, instead of inserting an `IcuUpdateOp` in the update
IR, we call `ingestBoundText` and use the presence of the surrounding
`IcuStartOp` and `IcuEndOp` to match the interpolation with the ICU.
PR Close#52698
Previously ICUs were assumed to only generate a single i18n expression
per ICU. However, it is possible for ICUs to contain text interpolations
which requires additional expressions. This commit adds support for
multiple expressions per ICU.
PR Close#52698
ICUs that contain element tags need extra parameters for the i18n
message. These are in addition to the element slot params that are
already added to the parent i18n block's params. In this commit we add a
new phase to fill in these placeholders.
PR Close#52698
Previously the template pipeline sorted i18n message params before
adding the sub-message placeholders. Now its sorts after all
placeholders are added.
Both the template pipeline and TemplateDefinitionBuilder previously
failed to sort the post-processing params. They both now sort these as
well. This is safe to change in TemplateDefinitionBuilder, as it does
not change anything about the functionality, it simply ensures that
params map in the output has the keys ordered in a way that can be
easily reproduced in the template pipeline.

Updates the repo to support TypeScript 5.3 and resolve any issues. Fixes include:
* Updating usages of TS compiler APIs to match their new signatures.
* In TS 5.3 negative numbers are represented as `PrefixUnaryExpression` instead of `NumericExpression`. These changes update all usages to account for it since passing a negative number into the old APIs results in a runtime error.

When a component contains `@defer` blocks, Angular compiler generates the code to apply component metadata (from the `@Component` decorator) after resolving all dynamic dependencies. Currently, this function is invoked eagerly at runtime, which causes dynamic imports to be kicked off earlier than expected. With the change in this commit, Angular will start resolving async metadata when it becomes necessary during testing.

Fixes that all implicit variables in `@for` loops were inferred to be numbers, even though most are actually boolean.
Note that I also had to work around a weird TypeScript behavior in `tsDeclareVariable` where usually we declare variables in the following format:
```
var _t1: <type> = null!;
```
This works in most cases, but if the type is a `boolean`, TypeScript infers the variable as `never`, instead of `boolean`. I've worked around it by adding an `as boolean` to the initializer.
Fixes#52730.

This change fixes a bug in the new list reconcilation algorithm
that could lead to an infinite loop in certain situations.
More specifically, it adjusts the internal MultiMap implementation
such that an entry returned from the .get call is the same entry
(for an identical key) removed by the .delete call.
The existing logic of the MultiMap was leading to a situation where
one view was requested and attached to LContainer, but a very different
view was removed from the MultiMap. This was leaving an attached LView
in a collection that was supposed to hold only detached views.

Rather than migrate all in one pass, this now migrates in a separate pass per control flow item plus one for templates at the end. This resolves issues with multiple control flow items on a single element as well as making sure ng-templates are fully migrated before being moved to new locations.

Now that two-way bindings work correctly with implicit receivers, we can fix the corresponing source map tests. The main issue was that we were not properly mapping `elementEnd` for elements with no closing tag (self-closing elements).
PR Close#52479
Some two-way bindings tests were not working properly, because we could not ingest the implicit receiver required to write to the `ngModelChanges` property. Now, we properly resolve that implicit receiver to the root component context.
Also, add some tests, both for the simple case, and the case where the listener is inside a nested view.

Some `defer` blocks have external dependencies on other components or directives. These dependencies need to be extracted into deps functions, which either return local deps, or use a dynamic import for non-local deps. Template Pipeline can now generate these functions.
PR Close#52479
When an `ng-template` has local refs, such as `<ng-template #foo>`, we must emit a `ɵɵtemplateRefExtractor` argument to the template creation functino. The template pipeline now supports this.
PR Close#52479
`TemplateDefinitionBuilder` is somewhat unreliable about extracting constant attributes (e.g. `[attr.foo]="'one'"`). It never extracts const non-string expressions, and usually, but not always, extracts const string expressions. Template pipeline consistently extracts const strings, and we add new goldens for a couple such cases.

Some defer triggers, such as `hover`, expect a local reference as an argument. For example, `@defer (on hover(target))` waits until the user hovers over the target.
However, these defer conditions also have a nullary form, in which the trigger is implicitly the first element in the placeholder block. We now support that case in template pipeline.
PR Close#52479
We already supported `defer on` conditions, which become instructions in the create mode block.
Now, we also support `defer when` conditions, where are very similar, with the notable difference that they go in the update block (because a user-supplied condition must be re-evaluated on each update.)
