touchui: Directly process key and mouse events.

Capture the keyboard and mouse events directly from X, create a corresponding
views::Event out of it, and send it to the associated RootView.

Includes Chad's (wyck) function FindRootViewForGdkEvent (from #3704005) slightly
modified (called FindRootViewForGdkWindow).

BUG=None
TEST=Click/Keypress events in a webpage should work correctly.
