[issue40098] dir() does not return the list of valid attributes for the object

[Serhiy Storchaka]

If using __class__ and __dict__ attribuites is a feature, it does not work for __getattr__(). I think it is confusing if __dir__() and __getattr__() are not consistent. I'll try to deal with unittes.mock and then will look how this will work with other classes that override __class__ or __dict__. Also we need to check all classes with custom __getattr__ for the matter of custom __dir__.

I think that it might be better if dir() for instance excluded names which are not accessed as via instance, e.g. non-descriptor class attributes and class methods. But it may be not easy to do.
