    bpo-32226: PEP 560: improve typing module (#4906)

    This PR re-designs the internal typing API using the new PEP 560 features.
    However, there are only few minor changes in the public API.


The reason seems that now all of the types are created using `_GenericAlias` 
that does not copy the `__name__` attribute.
