This changes the migration so that we don't generate `_1` suffixes when
a temporary variable wouldn't conflict with any variables in the lexical
scope.
In addition, if we discover conflicts, we try alternative suffixes that
seem more natural and follow style guides. E.g. `Value`, `Val` or
`Input`.

Currently we use some short variable names like `t` and `r` in the generated factory functions. They can conflict with local symbols with the same names, if they're used for DI.
These changes rename the parameters to reduce the change for conflicts.
Fixes#57168.

This commit addresses a performance bottleneck in the `interpolatedSignalNotInvoked` extended
diagnostic by querying directive metadata instead of consulting the type-checker to determine if
a property binding corresponds with an input.

These changes replace most usages of `removeChild` with `remove`. The latter has the advantage of not having to look up the `parentNode` and ensure that the child being removed actually belongs to the specific parent.
The refactor should be fairly safe since all the browsers we cover support `remove`. [Something similar was done in Components](https://github.com/angular/components/pull/23592) some time ago and there haven't been any bug reports as a result.

From the internal issue on the matter:
> When using the standard Jasmine version of it promises returned by the body function are automatically awaited. The Catalyst version of it is fake-async, so awaiting the promise does not make sense; however it would be nice if Catalyst automatically flushed the promise to replicate the experience of using standard it. This would allow users to do the following:
```
it('should fail later', async () => {
await new Promise(r => setTimeout(r));
fail('failure');
});
```
> In Catalyst today the above test will pass. If this proposal to automatically flush the resulting promise were implemented it would fail.
Flushing after the tests complete has been the default behavior inside
Google since 2020. Very few tests remain that use the old behavior of
only flushing microtasks. The example above would actually fail with
`fakeAsync` due to the pending timer, but the argument still remains the
same. We might as well just flush if we're going to fail the test
anyways by throwing if there's no flush at the end.
BREAKING CHANGE: `fakeAsync` will now flush pending timers at the end of
the given function by default. To opt-out of this, you can use `{flush:
false}` in options parameter of `fakeAsync`

Similar to a previous fix that intended to make the JIT transforms
compatible with pre-transforms like e.g. Tsickle, we need to solve
an additional issue where the class properties are synthetic and result
in an `getSourceFile() => undefined` invocation that breaks the import
insertion, causing errors like:
```
TypeError: Cannot read properties of undefined (reading 'fileName')
```

Angular's template files are not valid TypeScript. Attempting to get suggestion
diagnostics from the underlying TypeScript language service will result in
a large amount of false positives. Only actual TypeScript files should
be analyzed by the underlying TypeScript language service for suggestions.

This change is a proof of concept of how the new Chrome DevTools
Performance extension API (https://bit.ly/rpp-e11y) can be used to
surface Angular runtime data directly in the Chrome DevTools Performance
panel.
Specifically, it implements the following changes:
1. Use the profiling status notification API to toggle the Timing API:
The notification API is implemented under the
chrome.devtools.performance extension namespace and consits of two
events: ProfilingStarted and ProfilingStopped, dispatched when the
Performance panel has started and stopped recording, respectively. This
API is used to enable the Timings API when the recording has started in
the Performance panel and disable it when recording has stopped.
2. Use the User Timings `detail` field format specification of the
Performance extension API
(https://developer.mozilla.org/en-US/docs/Web/API/Performance_API/User_timing)
to inject data collected by the Angular Profiler into the
Performance panel timeline. Angular Profiler uses several hooks to
measure framework tasks like change detection. With this change, this
measurements are visible in the same context as the runtime data
collected by the browser in the Performance Panel timeline.
Note: to enable the user timings to be collected in the first place, one
needs to open the Angular DevTools panel so that the related artifacts
are loaded in the page. This shortcoming can be fixed in a follow up so
that the extra step isn't necessary.

Lock file maintenance updated Terser, which impacts the bundle
optimizations being tested via the symbol golden tests.
There was a small noticable change in the symbol golden where
`withDomHydration` is now preserved, and the underlying function
that was previously detected is gone. Seemingly Terser now inlines
this function and had to preserve `withDomHydration` as the entry point.

The new package comes with types by default, and also has a nicer

The old package had broken types and couldn't be used anymore; and
it's deprecated/unmaintained. We did a similar switch in
angular/dev-infra.

This commit is similar to 98ed5b609e, and
makes use of the preparation work implemented there.
Similar to directives and components marked via `jit: true`, we also
need to do the same for JIT marked `@NgModule` classes. This is mostly
important for downleveling of decorators to support dependency injection
of such classes.
Inside Google3, migrating from `ts_library` to `ng_module` turns of
decorator downleveling, so the `jit: true` for NgModule's is implicitly
requesting/reliant on this transform— as expected.

Rather than leaving the timers around as no-ops, this commit updates the
logic to also attempt to clear or cancel the timers. This is helpful for
the eventual goal of running the scheduler in the `fakeAsync` zone (if
the test is running in `fakeAsync`) rather than scheduling in the root
zone and making it impossible to flush.

This creates a private option that can be used internally while we
migrate this to the default and only behavior. ~200 tests in TGP have errors
that are being swallowed (console.log) and not causing the test to fail.
We can first explicitly opt those out, flip the default internally, then
"fix" them by adding expect...toThrow.
