Implement initial LayoutTransition for Taskbar recents.

Browse Source 
The animations mostly match the spec, though the recents indicators scale/fade with icon currently.

The change transitions need to incorporate translateX since that changes based on the number of icons in Taskbar. We need the translateX for pinning update to happen before TaskbarView lays out its children so that the animator computes the correct start and end values.
