This adds support for these methods through additional plugin hooks: * `pop` * `setdefault` * `update` (positional argument only) * `__delitem__` These methods also work and don't need plugin support: * `copy` * `has_key` (Python 2 only) * `viewitems` (Python 2 only) * `viewkeys` (Python 2 only) * `viewvalues` (Python 2 only) The base signatures for all of these methods are defined in `mypy_extensions._TypedDict`, which is a stub-only class only used internally by mypy. It becomes the new fallback type of all TypedDicts. Fixes #3843. Fixes #3550. There's some possible follow-up work that I'm leaving to other PRs, such as optimizing hook lookup through dictionaries in the default plugin, documenting the supported methods, and `update` with keyword arguments (#6019).
