This changes include mentioning the experimental application builder migration and changes to the `outputPath` and `optimization` option.

Previously, if an ICU was inside a nested i18n root, it would use the nested root to calculate whether it should be applied. Now, we use the root i18n block.

This commit adds compliance tests to ensure that the generated output of
signal-based queries matches our expectation.
Note: collapsing query advance instructions is not implemented yet.
PR Close#53978
This commit ensures that libraries can use signal-based queries, and the
partial compilation output will capture their metadata.
The linker is updated to support parsing this.
Two notes:
1. Older linker versions are not capable of parsing this, so the minimum
version for signal-based queries is adjusted when such are used.
2. We only emit `isSignal` metadata for queries when signal queries are
used. This enables libraries to continue supporting older linker
versions, if signal-based queries are not used.
PR Close#53978
Adds a compiler integration test for recognizing signal-based queries,
and emitting the expected output. Concrete output will be verified via
the compliance tests.

Currently, Angular tries to recognize string locators/predicates for
queries at compile time, and attempts to split multi-selector predicates
into an array as generated output. This is a a performance optimization.
In practice, this works most of the time because the compiler can detect
string locactors/predicates through static analysis.
Though, there are cases where it's not possible. That is when advanced
constructs are used, identifier references etc. that ultimately evaluate
to a string. Currently this breaks with queries and also surfaces now
with signal-based queries.

This commit uses the initializer API recognition that we built for
signal-based inputs, and teaches the compiler to recognize class members
that refer to `viewChild`, `viewChildren`, `contentChild` or
`contentChildren`. Those will declare signal-based view or content queries.

This commit introduces the compiler output generation for signal-based
queries. Signal-based queries will have new creation-mode instructions
and update instructions to advance the current query indices in the
global shared context.
An output like the following is the expected output for signal-based
queries:
```
i0.ɵɵdefineComponent({
viewQuery: function App_Query(rf, ctx) {
if (rf & 1) {
i0.ɵɵviewQuery(ctx.d, _c0, 5);
i0.ɵɵviewQuerySignal(ctx.ds1, _c0, 5);
i0.ɵɵviewQuerySignal(ctx.ds2, _c0, 5);
}
if (rf & 2) {
let _t;
// only change-detected queries need explicit refresh
i0.ɵɵqueryRefresh(_t = i0.ɵɵloadQuery()) && (ctx.d = _t.first);
// we bump up current query index by 2 positions since there are 2 signal-based queries
i0.ɵɵqueryAdvance(2);
}
…
},
…
});
```
Note: For now, the collapsing of multiple advance instructions is not
implemented. This will be a follow-up.
Note 2: A couple of query helpers are now in their own file. This makes
it easier to focus on query-specific compiler code. The new function is
called `createQueryCreateCall`, which is a modified variant of the
existing function that previously only generated query parameters.

The new `input` API is recognized using class member initializers.
We want to support similar APIs for queries, using e.g. `viewChild`
or `viewChild.required`.
This commit extracts the input recognition API and makes it reusable,
so that the same logic can be used to detect queries on a class member.
Additional changes:
- replacing `coreModule` with the simpler `isCore` parameter. This is
more readable.
- support for detecting a list of API names on a single class member.
This allows us to detect possible query functions on the same class
member without having to check X times. We simply check for the
initializer API pattern and check if one API function name matches.

At the moment local compilation breaks for host directives because the current logic relies on global static analysis. This change creates a local version by cutting the diagnostics and copying the directive identifier as it is to the generated code without attempting to statically resolve it.
PR Close#53877
At the moment when unified host is selected (through option `_useHostForImportGeneration`) the compiler always generates alias reexports. Such reexports are mainly generated to satisfy strict dependency condition for generated files. Such condition is no longer the case for G3. At the same time, these alias reexports make it impossible to mix locally compiled targets with globally compiled targets. More precisely, a globally compiled target may not be able to consume a locally compiled target as its dependency since the former may import from the alias reexports which do not exist in the latter due to local compilation mode. So, to make global-local compilation interop possible, it is required to be able to turn off alias reexport generation.

Node removal is immediate and does not require change detection to run
when animations are not provided. This refactor makes the animation
engine notify the scheduler rather than doing it on all node removals.

The devtools now support signals.
Writable signals of primitives are editable.
Object Signal and other non-writable signals (like computed) are not editable.

This commit adds extra logic to produce a diagnostic in case `@Component.deferredImports` contain types from imports that also bring eager symbols. This would result in retaining a regular import and generating a dynamic import, which would not allow to defer-load dependencies.

The new type testing infrastructure was introduced for the input-as-signals
authoring functions. This commit modifies this infrastructure to make it more
generic and support queries-as-signals.
