[igt-dev] [PATCH i-g-t v3 1/9] lib/intel_compute: Migrate xe_compute library to intel_compute

["Zbigniew Kempczyński" <zbigniew.kempczynski@intel.com>]

During my work on adding xe-compute support to DG2 I hit some issues
on Xe driver so instead of limiting workload to Xe only I decided to
handle i915 as well. Such attitude might be handy on driver feature
status comparison.

Patch does preparation step to share the code between i915 and Xe.

v2: Add intel_ prefix as compute code is in the library and globally
    visible (Kamil)
