vkd3d-shader/dxil: Generate specialized values in sm6_parser_emit_cast() for trivial casts.

Browse Source 
There is currently no need to make a special case for 16-bit
values, since the SPIR-V backend currently confuses them with
32-bit values. The generated VSIR code is not correct, but that
will have to be handled at a different level.
