audio: several fixes in audio routing callbacks
- audio policy:
Force device change to ensure new audio patch creation
upon first track activity on a given output.
Fix function device_distinguishes_on_address() which could mistake
some output device with remote submix input device.
- audio flinger:
Reduce number of binder calls upon new client registration by only
sending ioConfigChanged() callbacks to newly registered client.
Fix first patch after output thread creation not triggering an
ioConfigChanged() callback.
-audio system:
Force client registration upon routing callback installation to force
new ioConfigChanged() callback from audio flinger.
Bug: 22381136.
