This commit adds support for HLSL input semantics. User semantics are all semantics not starting with `SV_`. Those semantics ends up with a Location assignment in SPIR-V. Note: user semantics means Location, but the opposite is not true. Depending on the stage, some system semantics can rely on a Location index. This is not implemented in this PR.
