HLSL: various SPIR-V compute shader IDs must be a 3-vector of integers. This PR forces the external definition of SV_GroupID variables to 3-vectors. The conversion process between the shader-declared type and the external type happens in wrapped main IO variable conversion. The same applies to SV_DispatchThreadID and SV_GroupThreadID.
