[PATCH i-g-t 12/12] tests/kms_big_fb: Also test some CCS modifiers

[Ville Syrjala <ville.syrjala@linux.intel.com>]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Panning inside compressed framebuffers has similar challenges
as planar YCbCr framebuffers. So let's test this as well.
The difference is that i915 can't do GGTT remapping for CCS,
so we must limit the fb size to fit insie the hw limits.

Only enable this for the pre-TGL modifiers for now as testing
on TGL didn't go well. I suspect the problem lies with rendercopy
but until that is sorted let's not add tons of failures to CI.
