Fixing issue with exit animation due to incorrect visibility state.

- This CL ensures that only Recents updates the SysUI visibility state
  for itself, ensuring that the visibility state reflects the state in
  Recents, and allows us to skip unnecessary work to close system
  dialogs when it is not required.
