[PATCH v4 0/5] lib/gpgpu: add shader support

[Andrzej Hajda <andrzej.hajda@intel.com>]

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
