wined3d: Remove the atifs shader backend.

Since atifs is only doing the fragment pipeline replacement right now
there is no need for the shader backend structure any longer. The ffp
private data is stored in new fragment pipeline private data(which
could potentially be set to equal the shader private data if needed).
