Move remote animation definition runner to wrapped class

- Add call to unregister for remote animations from the system
  when the launcher activity is destroyed to prevent a lingering
  reference from the system to the old activity. But separately,
  to not have to wait for the system to GC before clearing the
  binder ref, we also wrap all runner implementations so that
  they can be cleaned up after a GC in our process only.
