chromeos: Implement power button animations for Aura.

This adds animated transitions first to the lock screen and
then to shutdown similar to those currently implemented in
the Chrome OS power manager and X window manager.  I'll add
support for the lock key in a later change.

BUG=98328
TEST=added tests; also did a lot of manual testing
