Fix instancing on D3D11 9_3, by ensuring slot zero contains non-instanced data D3D11 Feature Level 9_3 supports instancing, but slot 0 in the input layout must not be instanced. D3D9 has a similar restriction, where stream 0 must not be instanced. This restriction can be worked around by remapping any non-instanced slot to slot 0. This works because HLSL uses shader semantics to match the vertex inputs to the elements in the input layout, rather than the slots.
