This commit adds support by default for HTTP caching when using `provideClientHydration`. Users can opt-out of this behaviour by using the `withoutHttpTransferCache` feature.
```ts
import {
bootstrapApplication,
provideClientHydration,
withNoHttpTransferCache,
} from '@angular/platform-browser';
// ...
bootstrapApplication(RootCmp, {
providers: [provideClientHydration(withNoHttpTransferCache())]
});

This commit adds a provider function that allows developers to configure
the `NgZone` instance for the application. In the future, this provider
will be used for applications to specifically opt-in to change detection
powered by ZoneJS rather than it being provided by default.
This API does _not_ specifically provide support for developers to define their own
`NgZone` implementation or opt in to `NoopNgZone` directly. Both of
these are possible today, but are effectively unsupported (applications
that use these are left to their own devices to run change detection at
the appropriate times). That said, developers can still use DI in
`bootstrapApplication` to provide an `NgZone` implementation instead,
it's just not specifically available in the
`provideZoneChangeDetection` function.

`ng-app` is an AngularJS attribute, see https://docs.angularjs.org/api/ng/directive/ngApp. Using this attribute on a non AngularJS element can cause DI issues in AngularJS when running an AngularJS and Angular application on the same page.
As such, we avoid such problems the Angular `ng-app` attribute is renamed to `ng-app-id`.

This commit moves the providers for `NgZone`-based change detection to a
single provider function. This function is currently called by default
in all places where `NgZone` was provided
(`bootstrapApplication`, `bootstrapModule`, and `TestBed`).
When we want to make Angular applications zoneless by default, we
can make a public provider method that has to be used in order to enable
the zone change detection features. When this method is not called,
Angular would use `NoopNgZone` by default and not initialize any
subscriptions to the `NgZone` stability events.
Side note: There are actually two places that `NgZone` is provided for `TestBed`
(providers in `compileTestModule` and `BrowserTestingModule`). This
likely doesn't need to be in both locations.

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.

This commit moves the `TransferState` class implementation to `@angular/core`. This class will be needed in core in followup changes and `core` can not depend on `platform-browser` package.

Currently style of components using `encapsulation`, `None` or `Emulated` will not be removed from the DOM once the component get destroyed.
This change addresses this by keeping track of the number of times a component is rendered, when the component is destroyed the counter is decreased and once this reaches zero the style element is removed from the DOM.
Currently, this new behaviour is on opt-in bases, but it will be changed in the next major version.
To opt-in, set the `REMOVE_STYLES_ON_COMPONENT_DESTROY` DI token to `true`.
Example
```ts
@NgModule({
declarations: [
AppComponent,
],
imports: [
BrowserModule
],
providers: [
{ provide: REMOVE_STYLES_ON_COMPONENT_DESTROY, useValue: true }
],
bootstrap: [AppComponent]
})

ZoneJS is no longer loaded as an UMD, but instead is included as part
of the browser init entry-point. This means that ZoneJS is bundled and
the ESBuild logic needs to be adjusted for that.
PR Close#48521
`platform-browser` tests now run in ESM and with `.mjs` output, so
the build targets and tests need to be updated.
Here we change the `zone_event_unpatched` script to include the
`.init` suffix that will be picked up by `spec_bundle`.
Also some circular dependency tests are updated to refer to the
`.mjs` files.
PR Close#48521
Since Karma with Bazel does not support ESM natively, we bundle the
tests using ESBuild into a single AMD file. This not only solves the
ESM issue until we can run browser ESM tests natively (also pending
in the components repo - the esbuild generation follows ESM semantics
but since collapsed we don't rely on the real module system).
A benefit of bundling is also faster and more reliable Karma browser
tests since only a single file needs to be loaded- compared to hundreds
of individual files.
PR Close#48521
Since we generate a `.mjs` file as entry-point for jasmine tests,
a couple of issues prevented the transitive dependencies from
bootstrap targets to be brought in (causing resolution errors):
1. The `_files` (previously `_esm2015`) targets are no longer needed,
and they also miss all the information on runfiles.
2. The aspect for computing linker mappings does not respect the
`bootstrap` attribute from the `spec_entrypoint` so we manually
add the extract ESM output targets (this rule works with the aspect
and forwards linker mappings).
PR Close#48521
For every `ts_library` target we expose a shorthand that grants
access to the JS files because `DefaultInfo` of a ts library
only exposes the `.d.ts` files.
We rename this away from `es2015` since in practice it's a much
higher target these days. Additionally we no longer use the devmode
output but rather use the prodmode output which has the explicit
`.mjs` output- compatible with ESM.

This commit adds the `isEmpty` method to the `TransferState` class to make it possible to check whether the state is empty or not. This is helpful in situations when the `TransferState` should be serialized and the content is transferred to the client (if the state is empty - certain operations can be omitted).
PR Close#46915
This commit updates the `TransferState` to make it `providedIn: 'root'`. This makes the entire `BrowserTransferStateModule` module unnecessary, so it got deprecated as well.
The `ServerTransferStateModule` is still retained, but the `renderApplication` function now also includes the necessary tokens to serialize the `TransferState` automatically, so when using the `renderApplication` function, there is no need to include `ServerTransferStateModule` as well.
This change is a part of the ongoing efforts to update the shape of the FW APIs to make them standalone-friendly (so there is no need to import any NgModules).
PR Close#46879
On MacOS, pressing the alt key and another key turns into symbols, and
doesn't match the intended behavior. For example, `keydown.alt.s`
reports instead as `keydown.alt.ß`. We rely on the `key` field and not
the `code` field, which properly reports the code for S in this case.
This change adds support to allow users to specify they want to look at
the `code` field instead of the `key` field within their event string.
Example: `keydown.code.alt.leftshift` would only match the LeftShift and
not the right shift based on code values. It would also allow the user
to specify `keydown.code.alt.keys` to match S instead of ß when alt /
option is pressed on MacOS and would also work on Windows.

We have a file called `test-events.js` (named in an ambiguous way
anyway) that runs for all Karma web tests and configures ZoneJS to
not patch the `scroll` event. There are two issues:
1. The patch applies to all web tests. This could cause unexpected
issues.
2. The file is named ambiguously and also is placed at the project root,
in a wrong spot.
Additionally, the test doesn't even fail when the file is removed. This
commit applies the Zone config locally to the closest build target and
also reworks the test to actually ensure it's testing what it describes.

There are a couple of tests intentionally triggering and verifying
runtime errors thrown by `bootstrapApplication`. These errors are
also printed using the default `ErrorHandler`, while also being

pollute the test output with large amounts of text that make it
also seem like actual failing tests / something incorrect going on with

The Hammer.JS might be loaded asynchronously if the `HAMMER_LOADER` token is provided.
