Improve quick switch from home by tracking both x and y motion

- Add NoButtonQuickSwitchTouchController which uses
  BothAxesSwipeDetector to track horizontal and vertical motion.
- Initially, we only detect swipe left to right to quick switch
  (like before), but then we allow swipe up to either go to
  overview (if you hold) or back home (if you don't hold).
- xDisplacement transitions non-overview components out (e.g. shelf
  and workspace), and translates overview in.
- yDisplacement translates overview up and scales it down
