Propagate Latency to backend/system ports
...
Set accumulated capture-latency for physical-outputs
and accumulated playback-latency for physical-inputs
after Ardour is done setting all non-physical port latencies.
This will be needed for latency-compensation of the complete graph.

...
Theoretically one could alter the plugins after a delivery even on a
frozen track. ..or even change settings, the ordering and add/remove
plugins after the frozen part of a track.
We won't go there. Frozen is frozen. this API is not needed after all.
