  Log Message:
  -----------
  [DXIL][SPIRV] Lower `WaveActiveCountBits` intrinsic (#113382)

```
  - add codegen for llvm builtin to spirv/directx intrinsic in CGBuiltin.cpp
  - add lowering of spirv intrinsic to spirv backend in SPIRVInstructionSelector.cpp
  - add lowering of directx intrinsic to dxil op in DXIL.td

  - add test cases to illustrate passes
  - add test case for semantic analysis
```
  
Resolves #80176
