Reland: [DirectX] Add atan2 intrinsic and expand for DXIL backend (p1) (#109878)
This change is part of this proposal:
https://discourse.llvm.org/t/rfc-all-the-math-intrinsics/78294

This preliminary work adds the intrinsic to llvm and expands using atan
intrinsic for DXIL backend, since DXIL has no atan2 op.

Part 1 for Implement the atan2 HLSL Function #70096.

(reland #108865 reverted in #109842 due to doc build break)
