Matt Roper 3713ed52ef drm/xe: Add KUnit test for xe_pci.c IP engine lists
Add a simple KUnit test to ensure that the hardware engine lists for
GMD_ID IP definitions are sensible (i.e., no graphics engines defined
for the media IP and vice versa).

Only the IP descriptors for GMD_ID platforms are checked for now.
Presumably the engine lists on older pre-GMD_ID platforms shouldn't be
changing.  We can extend the KUnit testing in the future if we decide we
want to check those as well.

v2:
 - Add missing 'const' in xe_call_for_each_media_ip to avoid compiler
   warning.
