Fold to AOD animation: part 2, add fold to aod controller

Adds animation that animates AOD content
from left to right when folding a foldable
device.

There are still a couple of issue that should be
addressed in the follow up CLs:
* Navigation bar handle sometimes displayed on AOD
* Showing keyguard when folding from unlocked state
sometimes takes too much time so the screen blocker
times out which leads to flickering

Bug: 202844967
Test: fold from lockscreen, fold from unlocked device,
 aod enabled/disabled, gesture nav enabled/disabled
Test: screen off animation when unlocked
Test: screen off animation when locked
Test: screen off animation when timed out
Test: fingerprint unlock from aod
