Import WSGI types from _typeshed.wsgi

wsgiref.types is a new module in Python 3.11. Accordingly, typeshed's stubs were updated so that this module is only available from Python 3.11 onwards. But the typeshed-specific module _typeshed.wsgi (which is considered stable by typeshed) contains all the necessary definitions for all supported Python versions.
