Implement new expand arrow and apps grid

1. Add TransitionAnimationObserver to layout app list at the end of
   animation to make sure child views are in right position.
2. Replace old expand arrow icon with Skia-drawn arrow and implement the
   new transition.
3. Change the layout of apps grid and make the rows and cols adaptive to
   the width and height.
4. Enlarge the folder icon.
