[fx] Improve support for tuple subclasses such as NamedTuple (#73198) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/73198 Previously, if an arg to an FX node is a subclass of tuple then it gets sanitized essentially back to that base class. An example here is when setting an arg to be a TensorMetadata object, which is a NamedTuple, it will be set as a tuple instead. - Change `map_aggregate` to repack the tuple to `type(a)` when it's not directly a tuple (try/except for best attempt) - During codegen, call `add_global` for `type(a)` if it's not directly a tuple. - Add an option for an arg to provide a `_custom_fx_repr_fn` for use inside stringifying via `_format_arg` Test Plan: Added unit test coverage, where we inline the named tuple into arg/kwarg.
