JiaLiPassion 08b0c87a94 fix(zone.js): Promise.resolve(subPromise) should return subPromise (#53423)
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.

Alan Agius cb31dbc75c fix(zone.js): patch entire promise in node (#50552)
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.

Closes #50513, closes #50457, closes #50414 and closes #49930

JiaLiPassion d1ac3aa14e fix(zone.js): zone-node only patch Promise.prototype.then (#49144)
Close #47872

zone-node only patches `Promise.prototype.then` instead of patch
`Promise` itself. So the new NodeJS `SafePromise` will not complain
the Promise.prototype.then called on incompatible receiver.

We should also do this change on browser zone.js patch, but it will
be a big breaking change, because Promise.prototype.then will not work
with `fakeAsync` any longer.

Paul Gschwendtner cc5d3b75e2 refactor: update zone.js and tests to work with ESM (#48521)
* Adjusts tests to no longer rely on CommonJS features. Switches them to
  ESM
* Updates test initialization files to not double-initialize Jasmine now
  that bootstrap files are loaded after Jasmine. The `jasmine.boot`
  setup was hacky from `rules_nodejs` and will break in the future
  regardless if we e.g. use `rules_js` with actual unmodified `jasmine`.
