Animation for touch, wake and unlock

- Add callback to inform SysUI when the screen has been unblocked
and turned on.
- Cleanup inconsistent messaging about device interactive/screen on
and off.
- Add callbacks to inform SysUI about screen states
- Implement a quick fade for the scrim after touch, wake, and unlock.
  First, start with a black scrim on top of everything, and then fade
  it out.
- Make sure we play the normal unlock animation when device is pulsing
- Override navigation bar animations for touch, wake and unlock: Fade
  in the same manner as the scrim.
