anv/private: Modify aux slice helpers for Gen12 CCS

Browse source 
The isl_surf structs for Gen12's CCS won't describe how many slices in
the main surface can be compressed. All slices will be compressable if
CCS is enabled, so lookup the main surface's logical dimension.

v2. Add a space before a `?`. (Jordan)
