intel/blorp: Use the hardware op for CCS ambiguate on gen10+

Browse Source 
Cannonlake hardware adds a new resolve type in 3DSTATE_PS called
FAST_CLEAR_0 which does an ambiguate.  Now that the hardware can do it
directly, we should use that instead of binding the CCS as a render
target and doing it manually.  This was tested with a full Vulkan CTS
run on Cannonlake.
