drm/panthor: Add DEV_QUERY_GROUP_PRIORITIES_INFO dev query
Expose allowed group priorities with a new device query.
This new uAPI will be used in Mesa to properly report what priorities a
user can use for EGL_IMG_context_priority.
Since this extends the uAPI and because userland needs a way to
advertise priorities accordingly, this also bumps the driver minor
version.
v2:
- Remove drm_panthor_group_allow_priority_flags definition
- Document that allowed_mask is a bitmask of drm_panthor_group_priority
v3:
- Use BIT macro in panthor_query_group_priorities_info
- Add r-b from Steven Price and Boris Brezillon
