wined3d: Don't use floating point textures without ARB_texture_float. 

The floating point formats from ARB_texture_rg are only defined when
ARB_texture_float is also supported. It would have been nice if the formats
table itself was able to express this, but as far as I'm aware this is only an
issue for ARB_texture_rg, so it's probably not worth changing.
