Fix cycling of focusable panes in Chrome OS.

Update the ash window cycle controller so it can tell aura::Window to rotate
pane focus and pass it the cycle direction, rather than just activating each
window. The end result is that when you press Ctrl+Back and Ctrl+Forward
you get a consistent cycle now, going through all panes within the most
recently active browser window and then the launcher and status area.
