Protects against memory leaks. TaskViewTaskController adds itself to the
map when the object is created.

Bug: 369995920
Test: atest TaskViewTransitionsTest
Test: revert change to fix memory leak with BubbleTaskView cleanup,
  trigger a bubble and swipe to dismiss without opening it, observe from
  dump that TaskViewTransitions is holding on to the TaskViewContorller
  for that task, trigger a gc for systemui, observe that after gc the
  TaskViewController is cleared up from TaskViewTransitions
