C++ tree with path API

  • 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.
