wined3d: Constants in constants_set should always have a valid location in shader_glsl_load_constantsB().

D3DCOLOR_ARGB is a d3d8+ thing, ddraw has RGBA_MAKE.

This mostly affects the initial placement of the VBO. If an application really
does use a static buffer as if it was a dynamic one the driver is likely to
migrate it out of VRAM anyway, we shouldn't penalize more well-behaved
applications for that.
