    drm/xe: Add staging tree for VM binds
    
    Concurrent VM bind staging and zapping of PTEs from a userptr notifier
    do not work because the view of PTEs is not stable. VM binds cannot
    acquire the notifier lock during staging, as memory allocations are
    required. To resolve this race condition, use a staging tree for VM
    binds that is committed only under the userptr notifier lock during the
    final step of the bind. This ensures a consistent view of the PTEs in
    the userptr notifier.
    
    A follow up may only use staging for VM in fault mode as this is the
    only mode in which the above race exists.
    
    v3:
     - Drop zap PTE change (Thomas)
     - s/xe_pt_entry/xe_pt_entry_staging (Thomas)
