bluetooth/gst: Determine PA input/output caps in generic code

Browse source 
Make the code ever so slightly more generic by not using appsrc and
appsink in codec-specific logic when assigning caps specific to the raw
(PCM) format provided by or returned to PA.

Note that caps have to be set (= event) after starting, can't send
events in flushing state.
