  -----------
  [CIR][AMDGPU] Implement __builtin_amdgcn_*_dpp* builtins (#226469)

This commit implements the `__builtin_amdgcn_update_dpp`,
`__builtin_amdgcn_mov_dpp`, and `__builtin_amdgcn_mov_dpp8` builtins in
CIR, closely matching the implementation in
CodeGenFunction::EmitAMDGPUBuiltinExpr from OGCG.
