Screen off animation

SysUI can now control the screen off animation as long as
config_dozeAfterScreenOff is set to false.

The current implementation collapses the notification shade and moves
the clock whenever the use is on the lock screen, or will fade the
scrims and show the clock when the keyguard is occluded.

Display state change (on, doze, doze_suspended) is delayed to let the
animations occur at 60Hz.
