Remove region-output export (GUI)

This use-case is better served via stem-export.

This export mode never worked correctly when latent plugins
are present on the track. or when realtime export was chosen.

This used to call
  track.export_stuff() -> bounce_process()
periodically in small chunks from freewheeling callback,
which is no longer functional.
