[Review] level-zero and openpgl

[Luya Tshimbalanga]

Hello everyone,

both level-zero and openpgl are needed for review. level-zero is useful to support oneAPI
for Blender while openpgl 
is an optional dependency for Blender starting for 3.4.x release.

openpgl: https://bugzilla.redhat.com/show_bug.cgi?id=2151767

Thanks in advance,
