appDisplay: Add API to animate launch at given position

Add a `animateLaunchAtPos()` method to the AppIcon class to animate the
launch of an app at a given position. This allows for a visual
indication of whether dropping an app icon using DnD was successful at
the position the drop happened in a later commit.
