ash: Create new containers for PowerButtonController.

ash: Create new containers for PowerButtonController.

This nests ash's existing containers inside of three new
higher-level containers-of-containers.  The new higher-level
containers can be animated by PowerButtonController without
messing up transformations that have already been applied to
the lower-level containers.

BUG=114953
TEST=manual: locked and unlocked screen in compact mode with multiple browser windows
