[SR] Add various missing native ops (#71113)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/71113
This diff adds a variety of missing ~~out variants~~/native ops. Most of these are trivial, so I included them all in one diff.
Native ops
* `aten::mul` (list variant)
* `aten::sub` (int variant)
* `aten::add` (list variant)
* `aten::Int`
Out variants
* ~~`aten::gt`~~ (codegen will handle)
* ~~`aten::eq`~~ (codegen will handle)
