Revert 160696 - Decouple EventClientImpl and root window. Check containers on the same root window as focused window when testing if the focused window can receive events.  This was causing lock screen to lose focus when mouse is clicked on another root window.

This Cl also adds a debug build/linux desktop only shortcut (F11) to lock/shutdown.

BUG=152982
TEST=covered by test.
