{base,}sdk,hmi: Add WirePlumber policy roles
Add WirePlumber policy roles for Apertis based on Apertis Audio management
concept sample
This allows an audio player like Rhythmbox to be corked by the video
application, and restart playing when the video is done.
The WirePlumber alsa rules are specific for each hw devices, so this
overlay can be shared between SDK and HMI.
This will simplify WirePlumber overlay maintenance.
