App to home animation zooms into the app icon.

- Created FloatingIconView which is now used by both the app close and
  app open animation.
- getItemLocation in DeviceProfile is used to get an item's final location
  since getLocationOnScreen may return a View's location mid-animation.
- Added getFirstMatchForAppClose which is optimized to return for best
  visual animation.
- Also fixes app open RTL bug.
- Next CL will use AdaptiveIcons and FolderShape reveal animator to match
  the app icon to the app window.
