Trigger onTaskAppeared when a task started from recents becomes ready.

Launcher can now receive onTaskAppeared callback from
RecentsAnimationController to get remote animation target when in quick
switch mode.

Note: This CL just demonstrates how to receive callback and then
calling removeTask & finish recents animation,
in order to really improve quick switch flicking, launcher side needs
to implement the rest of logic to animate task's remote animation target
to make task switching more smoothly.
