wireplumber: Create new recipe for policy daemon

-carve out a new recipe for wireplumber policy, so that it
 can be assigned to the concerned container.
-create new packagegroup-pipewire-base capturing the set of
 packages required to use PipeWire API.
-remove the implicit dependencies between different wireplumber
 recipes, now each of those recipes will have to be included
 in the top level bb file.
-remove the wireplumber-config virtual package.
