OrientationManager manages the orientation.
There're some cases we need to reset the orientation of the top window:
- LockScreen is unlocked.
- An attention window is opened.
- All attention window is closed.
- TrustedUI is closed.
- sleepMenu is hidden.
Any of them occurs would trigger OrientationManager to dispatch
reset-orientation event and AppWindowManager would reset the
orientation of the active window.
