* Make tree_util.tree_flatten_with_path and tree_map_with_path APIs to be C++-based, to speed up the pytree flattening. * Moves all the key classes down to C++ level, while keeping the APIs unchanged. * Known small caveats: they are no longer Python dataclasses, and pattern matching might make pytype unhappy. * Registered defaultdict and ordereddict via the keypath API now.
