[igt-dev] [PATCH i-g-t 2/4] tests/i915/i915_pm_rpm: Modify gem-execbuf test for gen12+

From: Vikas Srivastava <vikas.srivastava at intel.com>

xy_color_blt is not supported on MTL and other gen12+ target
hence an IGT test update needs to be done. Modify the test
to add a lib API to check for xy_color_blt support.
