  Log Message:
  -----------
  [HLSL][SPIRV][DXIL] Implement `WaveActiveSum` intrinsic (#118580)

```    - add clang builtin to Builtins.td
      - link builtin in hlsl_intrinsics
      - add codegen for spirv intrinsic and two directx intrinsics to retain
        signedness information of the operands in CGBuiltin.cpp
      - add semantic analysis in SemaHLSL.cpp
      - add lowering of spirv intrinsic to spirv backend in
        SPIRVInstructionSelector.cpp
      - add lowering of directx intrinsics to WaveActiveOp dxil op in
    DXIL.td

      - add test cases to illustrate passespendent pr merges.
```
Resolves #70106
