My feeling is that we shouldn't accept a SM6 shader if the user specified a SM4 input. We should provide a new `VKD3D_SHADER_SOURCE_DXBC_DXIL` value in `enum vkd3d_shader_source_type` and accept a SM6 shader if that value was specified.

Out of convenience, we could also add something like `VKD3D_SHADER_SOURCE_DXBC`, which would allow any DXBC shader to be accepted. And possibly generalize it even further in order to autodetect SM1 too. I don't know if this would be useful for something.
