d89df144f0 jack-tunnel: run graph from JACK thread
Stop our own data-loop and enter/iterate/leave it from the jack thread.
This runs all our nodes in the JACK thread and removes 2 context
switches (jack to and from pw thread).

We can possibly do this nicer by only pushing our own streams onto a
new custom data-loop but that's for later.

73f5f7ae65 jack-tunnel: add a new 0-latency JACK sink/source module
Add a new JACK sink/source pair that translates to a single JACK
client.

The JACK playback port appears as PipeWire source and is processed
directly, synchronously, through the complete pipewire graph into
the PipeWire sink that is then made available on the JACK capture
ports.

Because all this happens in the same JACK cycle with no delay, the
latency is 0. A jack_iodelay on the JACK server has exactly the same
latency as the jack_iodelay on the PipeWire side.

The PipeWire sink and source are forced into the same rate and
buffer_size as the JACK server and can't dynamically change.

This only supports Audio for now.
