isl: Allow CCS in more cases (xe2)

Browse source 
By restricting these limitations up to GFX 12, CCS support
can be present on these cases that we think Xe2+ platform
should support compression.

Noticeably, CCS is allowed on depth resources without HiZ,
multi-sampled resources without CCS, and multi-sampled
stencil resources.
