d3d12: disable PIPE_CAP_SAMPLER_VIEW_TARGET

We can't currently support this correctly, because D3D12 doesn't allow
aliasing as freely as OpenGL does.

This can probably be supported eventually, by lowering to 2D-arrays
instead if 2D textures, for instance. But since this feature isn't
required for OpenGL 3.3, let's leave it for later.
