  -----------
  [X86][Clang] VectorExprEvaluator::VisitCallExpr / InterpretBuiltin - allow element extraction/insertion intrinsics to be used in constexpr #159753 (#161302)

FIXES: #159753

Enable constexpr evaluation for X86 vector element extract/insert builtins. and adds corresponding tests
Index is masked with `(Idx & (NumElts - 1))`, matching existing CodeGen.
