Handle Caps Lock short cut (Shift+Search) in ash [part 1 of 2].

Currently it's handled in chrome/browser/chromeos/system_key_event_listener.cc by checking the X event loop directly, but for Aura, it'd be better to remove the X dependency by moving the code to ash/accelerators/ since any class except aura::RootWindowHost should not handle an X event directly.
