    testsuite: Fix introspection test on Windows
    
    ...when we are using Python 3.8.x or later.  Python 3.8.x or later on Windows
    require one to call os.add_dll_directory() on every directory that contains
    dependent non-system DLLs of a module that are not bundled/installed with the
    module.
    
    Since we are very likely running programs that rely on dependent items in
    %PATH%, make things easier for people by calling os.add_dll_directory() on
    all the valid paths in %PATH% in api.py, so that the test will run
    successfully on Windows with Python 3.8.x or later.
