bpo-46469: Make asyncio generic classes return GenericAlias

These methods have existed since 3.9, but apparently aren't documented. Should the fix be backported?

You should probably also add these types to

cpython/Lib/test/test_genericalias.py

Line 52 in 82c5322

generic_types= [type, tuple, list, dict, set, frozenset, enumerate,

This should be backported.

There isn't any need to test it more than once and in the asyncio it tests both the c and python implementation so no need.

Sorry, @kumaraditya303 and @asvetlov, I could not cleanly backport this to 3.9 due to a conflict.
Please backport using cherry_picker on command line.
