Allow scalars for aliased binary ops {`multiply`, `subtract`, `divide`} (#65937)
Summary:
https://github.com/pytorch/pytorch/issues/65868 pointed out that the "long-form" versions of some binary ops like `mul`, `sub`, and `div` don't match their alias's behavior when it comes to handling scalar inputs. This PR adds the missing registration in `python_arg_parser.cpp` to resolve this.
