[fx] store Tracer class on Graph and GraphModule for package deserialization (#62497) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/62497 Previously named: add support for custom tracer in __reduce_package__ Stores a Tracer class on a Graph created by Tracer, and copies the Tracer class into the GraphModule's state so that when a GraphModule is packaged by torch package, it can be reconstructed with the same Tracer and GraphModule class name.
