  -----------
  [HLSL][clang] Add elementwise builtin for atan2 (p3) (#110187)

This change is part of this proposal:
https://discourse.llvm.org/t/rfc-all-the-math-intrinsics/78294

- Add HLSL frontend for atan2
- Add clang Builtin, map to new llvm.atan2
- SemaChecking restrict to floating point and 2 args
- SemaHLSL restrict to float or half.
- Add to clang ReleaseNotes.rst and LanguageExtensions.rst
- Add half-float-only-errors2.hlsl for 2 arg intrinsics, and update half-float-only-errors.hlsl with scalar case for consistency
- Remove fmod-errors.hlsl and pow-errors.hlsl now covered in half-float-only-errors2.hlsl

Part 3 for Implement the atan2 HLSL Function #70096.
