[PATCH v8 0/5] lib/gpgpu: add shader support

[Andrzej Hajda]

This patchset adds shader support to mainline IGT.
Together with iga64 inline assembly and demo test using both.

The patches were cherry-picked/trimmed from internal branch,
quite painful process. I hope I have not cut off too much :)

v3:
- bumped minimal meson version,
- use old string literals to satisfy clang
v4:
- bump meson to latest version supported by CI builder
v5:
- just small update, to ping potential reviewers :)
- revert back required meson version, instead use old syntax to make CI happy
v6:
- addressed most Kamil's comments - added docs for public functions,
  generator script moved to scripts, added ifdef guards to iga64_macros.h,
  fixed docs and description in xe_exec_sip test
v7:
- addressed checkpatch issues,
- removed "Driver requirement: xe" tag
v8:
- added sanity check for assemblies,
- added asserts after memory allocations,
- cosmetic changes,
- added r-b/a-b tags, one patch left :)
