drm/amd/display: move vmid determination logic to a module
Currently vmid is decided internally inside dc. With the introduction
of new asics we are required to coordinate vmid use with external
components.
This change converts vmid logic to a DAL module allowing vmid to be
passed in as a parameter to DC.
