[issue44318] Asyncio classes missing __slots__

[Serhiy Storchaka]

What is the problem with this?

Setting __slots__ is needed if we want to save memory for creating a lot of instances. It can also be used for preventing adding arbitrary attributes and/or making weak references. Setting __slots__ in base class is required if you want to get a benefit of setting __slots__ in any of subclasses.
