[PATCH i-g-t] lib/gpgpu_fill: Implement gpgpu_fill for XE3 which uses ugm intead of tgm

["Zbigniew Kempczyński" <zbigniew.kempczynski@intel.com>]

From: Dominik Grzegorzek <dominik.grzegorzek@intel.com>

Use ugm shared function (untyped 2d block store) instead of tgm
(typed 2d block store) on XE3 platforms.
