Currently we only check that the plane supports the pixel format of the fb we're about to feed to it. Extend it to check also the modifier, and more specifically that the combination of the format and modifier is supported.

I think Daniel Stone is on the hook to augment kms_ccs to properly test this all in igt. Would be nice to add the corresponding Testcase: lines when that's done.
With the test coverage gap addressed:
