keys: add PW_KEY_STREAM_CAPTURE_SINK

Browse source 
Add a property for capture stream to signal that they would like
to capture the output (monitor) of the default sink instead of the
default source.
Check the desired device we would like to capture from and handle
the capture from the sink by monitoring the monitor source.
