Finn Plummer 6d13cc9411 [HLSL] Implement WaveReadLaneAt intrinsic (#111010)
- create a clang built-in in Builtins.td
    - add semantic checking in SemaHLSL.cpp
    - link the WaveReadLaneAt api in hlsl_intrinsics.h
    - add lowering to spirv backend op GroupNonUniformShuffle
      with Scope = 2 (Group) in SPIRVInstructionSelector.cpp
    - add WaveReadLaneAt intrinsic to IntrinsicsDirectX.td and mapping
      to DXIL.td

    - add tests for HLSL intrinsic lowering to spirv intrinsic in
      WaveReadLaneAt.hlsl
    - add tests for sema checks in WaveReadLaneAt-errors.hlsl
    - add spir-v backend tests in WaveReadLaneAt.ll
    - add test to show scalar dxil lowering functionality

    - note that this doesn't include support for the scalarizer to
      handle WaveReadLaneAt will be added in a future pr

This is the first part #70104
