JiaLiPassion 008eaf3b7d fix(zone.js): should continue to executue listeners when throw error (#41562)
Close #41522

`zone.js` patches event listeners and run all event listeners together, if
one event handler throws error, the listeners afterward may not be invoked.

Reproduction:

```
export class AppComponent implements AfterViewInit {
  @ViewChild('btn') btn: ElementRef;
  title = 'event-error';

  constructor(private ngZone: NgZone) {}

  ngAfterViewInit() {
    this.ngZone.runOutsideAngular(() => {
      this.btn.nativeElement.addEventListener('click', () => {
        throw new Error('test1');
      });
      this.btn.nativeElement.addEventListener('click', () => {
        console.log('add eventlistener click');
      });
    });
  }
}
```

Until now no Angular users report this issue becuase in the `ngZone`, all
error will be caught and will not rethrow, so the event listeners afterward
will still continue to execute, but if the event handlers are outside of `ngZone`,
the error will break the execution.

This commit catch all errors, and after all event listeners finished invocation,
rethrow the errors in seperate `microTasks`, the reason I am using `microTask` here
is to handle multiple errors case.
