    drm/xe: Split TLB invalidation code in frontend and backend
    
    The frontend exposes an API to the driver to send invalidations, handles
    sequence number assignment, synchronization (fences), and provides a
    timeout mechanism. The backend issues the actual invalidation to the
    hardware (or firmware).
    
    The new layering easily allows issuing TLB invalidations to different
    hardware or firmware interfaces.
    
    Normalize some naming while here too.
