drm/xe/uapi: Remove unused flags

Those cases missed in previous uAPI cleanups were mostly accidentally
brought in from i915 or created to exercise the possibilities of gpuvm
but they are not used by userspace yet, so let's remove them. They can
still be brought back later if needed.

v2:
- Fix XE_VM_FLAG_FAULT_MODE support in xe_lrc.c (Brian Welty)
- Leave DRM_XE_VM_BIND_OP_UNMAP_ALL (José Roberto de Souza)
- Ensure invalid flag values are rejected (Rodrigo Vivi)

v3: Rebase after removal of persistent exec_queues (Francois Dugast)

v4: Rodrigo: Rebase after the new dumpable flag.

Fixes: dd08ebf ("drm/xe: Introduce a new DRM driver for Intel GPUs")
