[PATCH i-g-t v4 8/8] XE3: tests/intel/kms_frontbuffer_tracking: platform based handling of x-tile cases

[Clint Taylor <clinton.a.taylor@intel.com>]

From: Vinod Govindapillai <vinod.govindapillai@intel.com>

x-tile is not supported from xe3 onwards. Handle this conclusively
in all the kms_frontbuffer_tracking subtest options.
