Paul Gschwendtner 4e8c2c3422 refactor(core): static-query schematic should handle abstract classes (#29688)
Queries can not only be accessed within derived classes, but also in
the super class through abstract methods. e.g.

```
abstract class BaseClass {

  abstract getEmbeddedForm(): NgForm {}

  ngOnInit() {
     this.getEmbeddedForm().doSomething();
  }
}

class Subclass extends BaseClass {
  @ViewChild(NgForm) form: NgForm;

  getEmbeddedForm() { return this.form; }

}
```

Same applies for abstract properties which are implemented in the base class
through accessors. This case is also now handled by the schematic.
