Keep the position descriptor that GXClearVtxDesc leaves set

Browse Source 
Nintendo's GXClearVtxDesc, and Aurora's, keep GX_VA_POS at GX_DIRECT. The
HLE mirror cleared it to GX_NONE, so the next draw could publish no
position attribute and abort shader generation while a scene loads.
Keep the mirror in step, and give the shader a zero position if a
stream still arrives without one.

Ported from heurazy/Wiicompiled_VR-PLUS (c2b2500).
