wined3d: Get rid of last_was_foggy_shader & friends.

The fog settings do not depend on wether the shader writes to oFog or not, instead they depend on the FOGVERTEXMODE and FOGTABLEMODE settings, and if a vertex shader is bound at all. It works the same way as with the fixed function, and having a vertex shader is the same as using pretransformed vertices, just that the fog coord comes from the shader instead of the specular color: FOGTABLEMODE != NONE: The Z coord is used, oFog is ignored FOGTABLEMODE == NONE, with VS: oFog is used FOGTABLEMODE == NONE, no VS, XYZ: Z is used FOGTABLEMODE == NONE, no VS, XYZRHW: diffuse color is used
