add Session::transport_stopped_or_stopping() 

Session::TransportStateChanged notifies about transport stop before the stop is complete (i.e. at the start of the declick).
Various other objects (notably control surfaces) connect to this signal and use it to modify their displayed state.
We need a method that can tell them we are stopped (or stopping) even though we are not "fully" stopped yet. This is
that method
