Refactor various typing related issues (#4940)
* Add type annotations to ``visit`` & ``leave`` calls
This adds typing to most calls that visit nodes. All other changes are
due to mypy errors resulting from introduction of typing.
* Fix outstanding mypy issues
This removes some of the `type: ignore` comments in favour of
solving the mypy issues these comments were surpressing.
* Fix remaining references to node_classes
Except for two references to node_classes in the changelog this should be the last of them
