Dynamic audio policies: multi-zone through uid/device affinity

Setting audio device affinity for a given uid augments all
 audio mix criteria that do not route to the given devices
 to exclude the uid.
AudioPolicyManager: after changing the device affinity,
 check the outputs addressing the devices to re-evaluate
 audio routing

Bug: 111647296
Test: requires device with routing policy started by CarService
