First step for support WaveSize attribute in https://microsoft.github.io/DirectX-Specs/d3d/HLSL_SM_6_6_WaveSize.html and https://microsoft.github.io/hlsl-specs/proposals/0013-wave-size-range.html A new attribute HLSLWaveSizeAttr was supported in the AST. Implement both the wave size and the wave size range, rather than separately which might require more work. For #70118
