[PATCH i-g-t v3 2/3] tests/intel/xe_ccs: require flat CCS on xe2

[Matthew Auld <matthew.auld@intel.com>]

On Xe2 compression is handled via PAT indexes and flat CCS, even on
igpu. Ensure the device has flat CCS support on such hardware, to
determine if these tests are valid.

v2: (Zbigniew)
 - There is at least one uncompressed test also, which is valid
   regardless of CCS. Move the skip deeper.
v3:
 - HAS_FLATCCS() expects dev_id.
