[igt-dev] [PATCH i-g-t] lib/intel_batchbuffer: Use COMPUTE instead of RENDER engine for Xe if missing

[Dominik Grzegorzek]

Make engine fallback in intel_batchbuffer more generic. Up to this
point, we were replacing render with compute only on PVC.
Replace it whenever there is no compute engine. As was stated in
989920cfc4 this still remains only a workaround, more rework
in intel-bb is necessary to better support both - i915 and xe.
