That's an updated version of my previous KUnit RFC series:
	https://patchwork.freedesktop.org/series/110481/

While the RFC series added support for live and perf, let's start with
mock, as running tests in bare metal is not the current focus of KUnit.
So, basically patch 1 was changed to export just mock functions,
and the bare metal patches got removed from this version.

As before, running KUnit on i915 driver requires the --arch parameter:

./tools/testing/kunit/kunit.py run --arch=x86_64 --kunitconfig=drivers/gpu/drm/i915/selftests/  --jobs=`nproc --all`
