lib/igt_fb: Add support for the gen12 media compressed modifier
Media compressed framebuffers don't have a CCS CC plane. Add helpers to
select the different types of CCS planes and make sure we setup the
planes correctly for MC framebuffers too.
Note that the order of MC framebuffer planes this change assumes is
plane 0: Y plane
plane 1: UV plane
plane 2: CCS plane for plane 0
plane 3: CCS plane for plane 1
unlike the order defined in the latest decompression kernel patchset.
The above order is the logical one that allows us to keep the existing
way of handling the Y/UV planes.
v2:
- Fix is_ccs_plane() adding the missing is_ccs_modifier() check.
v3:
- Simplify is_ccs_plane(). (DK)
