that is enabled if the nested navigation contexts is created by the navigator.

of the navigator component.
Summary:
Per offline discussion with @evv, we'd like to deprecate the `onDidFocus` and `onWillFocus`
API that makes it really hard for the descendent children of a navigator to observe its focus
change events.
@public
Since for now the descendent children do have access to the navigator via `this.props.navigator`,
this diff makes it easy to observe the focus change event by doing:
```
this.props.navigator.addListener('willfocus', this._onFocus);
```
The goal is to make the event system in navigator more useful and maintainable.
Test Plan:

1. jest: ./Libraries/FBReactKit/js/runTests.js NavigationEventEmitter
2. Load UI Explorer: <Navigator />, see console logs that shows the focus change events fires.
