3. audio policy: fix global effect attachment

Fix logic for global music effects (e.g Visualizer) attachement to
output streams.
- Consider only outputs with active music sessions first and then all
outputs
- Reevaluate effect attachment systematically on music playback start/stop
and when outputs are opened/closed
- Use the same logic every where.
