Matt Atwood c94fde8f51 drm/i915/uapi: Add DRM_I915_QUERY_GEOMETRY_SUBSLICES
Newer platforms have DSS that aren't necessarily available for both
geometry and compute, two queries will need to exist. This introduces
the first, when passing a valid engine class and engine instance in the
flags returns a topology describing geometry.

Based on past discussion, we currently only support this new query item
on Xe_HP and beyond; earlier platforms do not need to worry about
geometry and compute pipelines having access to different topology and
should continue to use the existing topology query.

v2: fix white space errors
v3: change flags from hosting 2 8 bit numbers to holding a
i915_engine_class_instance struct
v4: add error if non rcs engine passed.
v5 (by MattR):
 - Improve kerneldoc and cross references to related structs/enums.
   (Daniel)
 - Clarify that geometry query is only supported on render engines
   (Francisco)
 - Clarify that the new query is only supported on Xe_HP+.
 - Fix checkpatch warnings.
