[PATCH i-g-t v5 7/7] tests/intel/kms_frontbuffer_tracking: fix x-tiled tests for case when there is no x-tile

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

From: Juha-pekka Heikkila <juha-pekka.heikkila@intel.com>

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

v2: Optimize display_ver checks (Sai Teja)
