wined3d: Allow using the HLSL FFP replacement with GL.

Browse source 
This will allow us to replace the GLSL FFP pipes, and is useful for testing
the FFP HLSL backend before the Vulkan backend is mature enough in other
respects.

This patch introduces the d3d setting "ffp_hlsl", set to a DWORD value.
It is disabled by default, and only has an effect on the GL renderer.
