Reland "chromeos: Move several power-related classes to Ash"
This reverts r227562 to reland r227544.
Original description: "Move SuspendObserver,
UserActivityNotifier, and VideoActivityNotifier from
chrome/browser/chromeos/power to ash/system/chromeos/power."
This iteration makes ash::Shell's destructor destroy
VideoActivityNotifier before VideoDetector to avoid a
use-after-free.
BUG=none
