Tobias Bosch 630028350a refactor(core): Introduce AppInitStatus
This class allows any provider to know and wait for the initialization of the
application. This functionality previously was tied to `ApplicationRef`.

BREAKING CHANGE:
- `ApplicationRef.waitForAsyncInitializers` is deprecated. Use 
  `AppInitStatus.donePromise` / `AppInitStatus.done` instead.
