If a library is compiling with Angular v16.1.0, the library will break
for users that are still on Angular v16.0.x. This happens because the
`DirectiveDeclaration` or `ComponentDeclaration` types are not expecting
an extra field for `signals` metadata. This field was only added to the
generic types in `16.1.0`- so compilations fail with errors like this:
```
Error: node_modules/@angular/material/icon/index.d.ts:204:18 -
error TS2707: Generic type 'ɵɵComponentDeclaration' requires between 7 and 9 type arguments.
```
To fix this, we quickly roll back the code for inserting this metadata
field. That way, libraries remain compatible with all v16.x framework
versions.
We continue to include the `signals` metadata if `signals: true` is set.
This is not public API anyway right now- so cannot happen- but imagine
we expose some signal APIs in e.g. 16.2.x, then we'd need this metadata
and can reasonably expect signal-component library users to use a more
recent framework core version.

The component exposed by the fixture is not important thus marked as `unknown`.
Exposing the fixture of the `RouterTestingHarness` allows to use the methods & properties of that fixture and makes it compatible with testing libraries relying on `ComponentFixture`

If the compiler CLI is running through closure compiler, the trait
decorator handlers are converted from classes to functions as ES5
is picked as default output target for the bundled version.
The problem is that currently all trait handlers end up having the
same `name`. i.e. an empty string, and therefore adopting previous
traits from a previous build iteration result in the incorrect handler
being used for e.g. registrering, compiling etc- causing
ambiguous/confusing errors down the line in other parts.
We can look into changing the output target in the future, but even
then we are safer using an actual literal due to property renaming.
```$$closure$$NgModuleDecoratorHandler = function() {}`.
It is is questionable if we should just simply NOT run the compiler
through JSCompiler.

Before this commit, links to methods had to rely on a custom title (or the method name would be displayed).
With this commit, {@link MyClass#myMethod} will ouput a link as `MyClass#myMethod`.
This has a 2nd advantage : We can now rely on the validation by the `checkAnchorLinksProcessor` to ensure the method actually exist.
This commit is part of #50110 to improve linking in the documentation.

Extend toSignal to accept any Subscribable (instead of only Observable)
for consistency with AsyncPipe and for broader compatibility with any
observable library (that is compatible with the Subscribable interface).
This is only a type change as the implementation does not use anything
else than the Subscribable interface anyway.

Angular's null-safe access operators differ from Javascript's built-in semantics, in that they short-circuit to `null` instead of `undefined`. This necessitates providing a custom transformation, instead of relying on Typescript or Javascript itseld.
The old TemplateDefinitionBuilder uses a top-down approach based on the Visitor pattern, in which it recursively extracts the left-most safe access, and hoists it to a null check at the top. See `expression_converter.ts` for details.
In this commit, we replace that approach with a new bottom-up algorithm, as part of the template pipeline. This requires an intermediate expression type to represent the not-yet-expanded ternary operators, and is split into its own pass.
Null-safe function calls are not yet implemented, since they will rely on a future temporary variable allocation pass.

Create a pass that expands nullish coalescing operators into null checks.
This is not yet finished because we need to emit temporary variable assignments, which we will do using a future temporary variable allocation pass. Also, TemplateDefinitionBuilder is a bit quirky, and we still need to exactly match its behavior.
Nevertheless, this is good enough to prevent the diffs from getting ruined as a result of nullish coalescing operations.

It is sometimes useful to clone an expression tree, in order to copy it and mutate it in a phase, without affecting other subtrees due to the copy-by-reference.

Add missing attribute ingesiton for templates
Unify how template and element bindings are ingested
This resolves the issue of missing listener attributes on templates. In
order to avoid emitting extraneous instructions, listener ops on
templates are stripped in the attribute extraction phase instead.
Handle different binding types separately in ingest
Cleanup code and comments
Disable test that fails on new explicit error.
Previously the test was passing because ingestPropertyBinding treated
attribute bindings as normal bindings which happened to be ok for the
particular test. Now there's an explicit error that attrbiute bindings
aren't yet handled which causes the test to fail
