Allow recents animation controller to control input consumer lifecycle

- Removing race between the system cleaning up the input consumer and the
  controller who is also managing the input consumer lifecycle (it's
  preferable for the controller to keep the input consumer registered,
  and only to toggle the enabled state).  Instead, we only ensure that we
  clean up if the runner is unexpected destroyed.
- Also ensure that we don't add the input consumer on top of the runner's
  app window
