Add some basic unit tests for rtp. This is intended to prove the
functionality of the rtp itself, like coalescing entries, rejecting
non-disjoint values, etc.
Contrary to the other tests in xe, this is a unit test to test the
sw-side only, so it can be executed on any machine - it doesn't interact
with the real hardware. Running it produces the following output:
$ ./tools/testing/kunit/kunit.py run --raw_output-kunit \
--kunitconfig drivers/gpu/drm/xe/.kunitconfig xe_rtp

Note that the ERRORs in the kernel log are expected since it's testing
incompatible entries.
v2:
- Use parameterized table for tests (Michał Winiarski)
- Move everything to the xe_rtp_test.ko and only add a few exports to the
right namespace
- Add more tests to cover FIELD_SET, CLR, partially true rules, etc
