Add temporary impl_UNBOXED syntax sugar for unboxed-only defs. (#35714)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/35714
There are a lot of unboxed only defs. We're committed to removing
them at the end of the half but as I am about to do a lot of porting
to the new API, let's get them into a form where they're easy to
remove. This is a new overload impl_UNBOXED that will pass
the function pointer straight to CppFunction::makeUnboxedOnly
I don't attempt to make the _UNBOXED API complete; in particular,
catchall declarations don't get this sugar (as there are very few
of them).
