    Activate Python "Limited API" in PL/Python
    
    This allows building PL/Python against any Python 3.x version and
    using another Python 3.x version at run time.  This is useful for
    installers that want to run against a separately downloaded Python, so
    that they don't have to bundle it themselves.
    
    This builds on the earlier patch to only use APIs supported by the
    Limited API.
    
    At the moment, this is not activated on MSVC because that leads to
    build failures that no one could explain or cared enough to address.
    This could be done later.
