[docs] [issue22275] asyncio: enhance documentation of OS support

[STINNER Victor]

New submission from STINNER Victor:

When reading asyncio documentation, it's not easy to catch limitations of each operating system and event loop. I propose to mention in each mention if the method is not supported in some cases. See attached patch.
