D3D11: Query for output merger logic op support and use logic op code only if supported

Browse source 
Previously code assumed that if DX11.1 runtime is supported, logic ops will,
but Windows 7 SP1 with a Platform Update supports DX11.1 runtime without logic ops.
This created pretty jarring visual artifacts, which now should be gone OR replaced
with much less jarring errors.
