JiaLiPassion dea7234a76 fix(zone.js): async-test should only call done once (#45025)
`AsyncTestZoneSpec` triggers jasmine `done()` function multiple times
and causes warning

```
An asynchronous function called its 'done' callback more than once. This is a bug in the spec, beforeAll, beforeEach, afterAll, or afterEach function in question. This will be treated as an error in a future version. See<https://jasmine.github.io/tutorials/upgrading_to_Jasmine_4.0#deprecations-due-to-calling-done-multiple-times> for more information
```

The reproduce case will be running some `Zone.run()` inside
`waitForAsync()`.

```
it('multiple done', waitForAsync(() => {
  Zone.current.run(() => {});
  Zone.current.run(() => {});
}));
```

The reason the `done()` is called in the `onInvoke()` hook is to handle
the case that the testBody is totally sync, but we should only do this
check for the entry function not for all `Zone.run()` scenario.

Another issue is if we run nested zone inside `waitForAsync()`, the
`onHasTask()` hook will be triggered multiple times, and cause `done()`
be triggered multiple times, so we need to only trigger the `done()`
when the zone is `AsyncTestZone`.
