impl-port: add port.group property

Browse source 
Can be used to group ports together. Mostly because they are all from
the same stream and split into multiple ports by audioconvert/adapter.

Also useful for the alsa sequence to group client ports together.

Also interesting when pw-filter would be able to handle streams in the
future to find out what ports belong to what streams.
