[PATCH 4/5] wined3d: Don't use depth textures without ARB_depth_texture.

[Stefan Dösinger]

This is a fairly academic change because the FBO attachability test
already prevents us from using textures as depth attachments. It
prevents applications from using hypothetic depth textures that are
uploaded like normal textures instead of rendered to. It applies only to
D24S8 textures because other formats have the ARB_DEPTH_TEXTURE check in
the format table.
