This commit updates the implementation of the `customElements` patch and also
patches FACE callbacks (`formAssociatedCallback`, `formDisabledCallback`, `formResetCallback`
and `formStateRestoreCallback`). This now allows invoking those callbacks in the same zone
where the custom element has been defined.

This commit updates the implementation of the zone.js `fs` patch to
restore the implementation of `realpath.native` and patches it as a macrotask,
along with other functions of the `fs` package. This is the only nested function
that must be patched.

This commit updates the implementation of the `fetch` patch and additionally
patches `Response` methods which return promises. These are `arrayBuffer`, `blob`,
`formData`, `json` and `text`. This fixes the issue when zone becomes stable too early
before all of the `fetch` tasks complete. Given the following code:
```ts
appRef.isStable.subscribe(console.log);
fetch(...).then(response => response.json()).then(console.log);
```
The `isStable` observer would log `false, true, false, true`. This was happening because
`json()` was returning a native promise (and not a `ZoneAwarePromise`). But calling `then`
on the native promise returns a `ZoneAwarePromise` which notifies Angular about the task
being scheduled and forces to re-calculate the `isStable` state.

Currently the ZoneJS typing tests executes outside of Bazel, as a legacy
artifact of the monorepo merging (as it seems - not ideal at all).
Looks like this test relies on its own node modules, that were NOT
locked using a yarn lock file. This commit adds one, and specifically
locks it to a `@types/node` version that does not include the most
recent patch release (which seemingly introduced a breaking change)
that causes issues with TypeScript's lib checking.
Whenever we perform lock file maintenance in the future, we have the
following options:
- Consider disabling lib checking via `skipLibCheck` for this test. This
may be acceptable.
- Continue locking the node version,
- Waiting for chokidar to comply with the new signature
- Waiting for the breaking change to be rolled back.

fetch support AbortSignal, zone.js schedules a macroTask when fetch()
```
fetch(..., {signal: abortSignal});
```
we should also be able to cancel fetch with `zoneTask.cancel` call.
So this commit create an internal AbortSignal to handle
`zoneTask.cancel()` call and also delegate the `options.signal` from the
user code.

```
const ac = new AbortController();
addEventListener(eventName, handler, {signal: ac.signal);`
ac.abort();
```
Currently `zone.js` doesn't support the `signal` option, this PR allows
the user to use AbortContoller to remove the event listener.

The `nodejs-websocket` package has been replace with the `ws` package.
Both provide `WebSocket` server support and both of zero transitive
dependencies. However, the `ws` package has ~78 million weekly downloads
and was last updated this week (as of the writing of this commit) while
the `nodejs-websocket` package has ~7,600 weekly downloads and was last
update 5 years ago. The `ws` package is also already a transitive dependency
of the repository which allows for a reduction in the total dependency count
for the repository.

In the original `Promise` impelmentation, zone.js follow the spec from
https://promisesaplus.com/#point-51.
```
const p1 = Promise.resolve(1);
const p2 = Promise.resolve(p1);
p1 === p2; // false
```
in this case, `p2` should be the same status with `p1` but they are
still different instances.
And for some edge case.
```
class MyPromise extends Promise {
constructor(sub) {
super((res) => res(null));
this.sub = sub;
}
then(onFufilled, onRejected) {
this.sub.then(onFufilled, onRejected);
}
}
const p1 = new Promise(setTimeout(res), 100);
const myP = new MyPromise(p1);
const r = await myP;
r === 1; // false
```
So in the above code, `myP` is not the same instance with `p1`,
and since `myP` is resolved in constructor, so `await myP` will
just pass without waiting for `p1`.
And in the current `tc39` spec here https://tc39.es/ecma262/multipage/control-abstraction-objects.html#sec-promise-resolve
`Promise.resolve(subP)` should return `subP`.
```
const p1 = Promise.resolve(1);
const p2 = Promise.resolve(p1);
p1 === p2; // true
```
So the above `MyPromise` can wait for the `p1` correctly.

Before this commit, zone.js wraps the uncaught promise rejection error
to a new Error object includes more information such as Zone stack
traces. This feature is provided from the very beginning of Zone.js,
but this feature becomes very annoying and make the user difficult to
debug.
So this commit disable this wrapping behavior by default, and user can
enable this feature back by setting
`DISABLE_WRAPPING_UNCAUGHT_PROMISE_REJECTION` to `false`.

A lot of our tests are wrapped in `{}` which serves no purpose, aside from increasing the nesting level and, in some cases, causing confusion. The braces appear to be a leftover from a time when all tests were wrapped in a `function main() {}`. The function declaration was removed in #21053, but the braces remained, presumably because it was easier to search&replace for `function main()`, but not to remove the braces at the same time.

This commit removes access to deep imports and `zone-testing-bundle` and `zone-testing-node-bundle`
This commit removed access to deep and legacy `dist` imports. `zone-testing-bundle` and `zone-testing-node-bundle` are also no longer generated.
BREAKING CHANGE:
Deep and legacy `dist/` imports like `zone.js/bundles/zone-testing.js` and `zone.js/dist/zone` are no longer allowed. `zone-testing-bundle` and `zone-testing-node-bundle` are also no longer part of the package.
The proper way to import `zone.js` and `zone.js/testing` is:
```js
import 'zone.js';
import 'zone.js/testing';
```

In https://github.com/angular/angular/pull/49144 we introduced a change to only path `Promise.prototype.then` due to Node.js `SafePromise` complaining about `Promise.prototype.then` called on incompatible receiver. This however introduced a number of regressions. This commit reverts this change and re-introduces the changes to patch the entire promise on Node.
The original `SafePromise` problem is no longer reproducible as of Node.js version 18.13+ as it was addressed as part of https://github.com/nodejs/node/pull/45175.
While the Angular CLI does not yet generate ESM server bundles, users using ESM with dynamic imports will require using Node.js 18.13 or later.
