vo_direct3d: remove non-working nv12 shader support

It never worked. It relied on some obscure texture format to provide the
equivalent of GL_RG or GL_LUMINANCE_ALPHA, but no hardware seemed to
report support for it ever. No idea what's the correct way to do this.
On D3D11 it exists, of course.

(Actually I'd like to remove the whole VO.)
