[homekit] improve bundle deactivation time (#13566) 

If you have many instances, it can take a while. So stop all the
instances in parallel. Also, fix a race condition where the update
debouncer might get called again after being stopped, because the
change listener was deregistered _after_ the debouncer was stopped.
