In order to investigate the performances of SSR, this commit introduces a benchmark suite which will measure several step of the rendering.

In Bazel, the `CI` environment variable is not set due to its hermetic nature. As a result, caching is enabled by default, which includes Vite pre-bundling. This is unnecessary in CI environments.
In some cases, this leads to errors during CI runs when the Vite build is closed or canceled prematurely, resulting in the following errors:
```
Error: R] The build was canceled
Error: R] Terminating worker thread [plugin angular-vite-optimize-deps]
```

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.

This commit also performs lock file maintenance on all integration
tests, fixing some ambigous ESM/CJS dependency graph issues.
e.g.
```
Unknown error: Error [ERR_REQUIRE_ESM]: require() of ES Module /tmp/ng-integration-test-aTpQOT/test-sandbox/node_modules/string-width/index.js from /tmp/ng-integration-test-aTpQOT/test-sandbox/node_modules/cliui/build/index.cjs not supported.
Instead change the require of index.js in /tmp/ng-integration-test-aTpQOT/test-sandbox/node_modules/cliui/build/index.cjs to a dynamic import() which is available in all CommonJS modules.

Adds `output()` to the signal inputs integration test to verify
full integration with the Angular CLI. In the future we may
consider renaming the test to something less specific to signal inputs,
but for now this serves the purpose and `output()` is a closely related
part to signal-based inputs.
it doesn't warrant creating another new integration test, as those are
quite expensive to maintain and run.

Enables signal inputs for existing Zone based components.
This is a next step we are taking to bring signal inputs earlier to the Angular community.
The goal is to enable early access for the ecosystem to signal inputs, while we are continuing
development of full signal components as outlined in the RFC. This will allow the ecosystem
to start integrating signals more deeply, prepare for future migrations, and improves code quality
and DX for existing components (especially for OnPush).
Based on our work on full signal components, we've gathered more information and learned
new things. We've improved the API by introducing a way to intuitively declare required inputs,
as well as improved the API around initial values. We even support non-primitive initial values
as the first argument to the `input` function now.
```ts
@Directive({..})
export class MyDir {
firstName = input<string>(); // string|undefined
lastName = input.required<string>(); // string
age = input(0); // number
```
PR Close#53872
This commit adds a transform for supporting input signals in JIT
environments. The transform will be wired up for Angular CLI
applications automatically. An integration test verifies that this fixes
unit testing with signal inputs.
The transform basically will take the signal input metadata and
transform it into `@Input` decorators that can provide static
information to the Angular JIT runtime when the directive/component
definition is compiled.

The repository currently has two globbing packages. To minimize the number of packages in
the framework repository, the uses of the `glob` package are being converted
to `fast-glob` which is used by the tooling repository. The change is mostly mechanical
and in this change the build and test scripts are converted.

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.

Prior to this commit relative HTTP requests were not being resolved to absolute even thought the behaviour is documented in https://angular.io/guide/universal#using-absolute-urls-for-http-data-requests-on-the-server.
This caused relative HTTP requests to fail when done on the server because of missing request context. This change is also required to eventually support HTTP requests handled during prerendering (SSG).

`tsickle` is not used in any code paths in 3P and we can remove
this complexity. The `tsickle` npm package has not been released
in a while and we are risking breakages with e.g. future TypeScript
versions.
Note that the `ng_module` rule was updated to not emit through
tsickle at all. The tsickle in 1P is done directly by `tsc_wrapped`
and our code path in `compiler-cli` is not needed at all.

This commit updates the `@angular/common/http` and `@angular/platform-server` packages to allow dynamic import of the `xhr2` dependency. The `xhr2` dependency has side-effects that rely on a global scope and as a result in some environments those side-effectful calls fail. With the changes from this PR, the import is delayed until it's actually needed, which gives a chance for the underlying platform to setup global scope (via shims) as needed.

This commit adds a background macrotask when an XHR request is performed. The macrotask is started during `loadstart` and ended during `loadend` event.
The macrotask is needed so that the application is not stabilized during HTTP calls. This is important for server rendering, as the application is rendering when the application is stabilized.
The application is stabilized when there are no longer pending Macro and Micro tasks intercepted by Zone.js, Since an XHR request is none of these, we create a background macrotask so that Zone.js is
made aware that there is something pending.
Prior to this change, we patched the `HttpHandler` in `@angular/platform-server` but this is not enough, as there can be multiple `HttpHandler` in an application, example when importing `HttpClient` in a lazy loaded component/module.
Which causes a new unpatched instance of `HttpHandler` to be created in the child injector which is not intercepted by Zone.js and thus the application is stabalized and rendered before the XHR request is finalized.
NB: Zone.js is fundamental for SSR and currently, it's not possible to do SSR without it.

Prior to this change component styles generated on the server where removed prior to the client side component being rendered and attached it's own styles. In some cases this caused flickering. To mitigate this `initialNavigation: enabledBlocking'` was introduced which allowed the remove of server styles to be defer to a latter stage when the application has finished initialization.
This commit changes the need for this, by not removing the server generated component styles and reuse them for client side rendering.
