Add support for boxed functors (#62658) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/62658 Boxed functors, like their unboxed brethren, support operators which aren't just a function pointer, but a function pointer with some associated global state that is allocated at registration time. The use case I have in mind with this implementation is "dispatcher API from Python", where the extra state kernel registrations need is the PyObject callable we will invoke to do the actual invocation. See next PR in this stack. Signed-off-by: Edward Z.
