[issue33219] x in IntFlag() should test int x's inclusion in IntFlag

Ethan Furman added the comment: Nitish, Flag can check if the current Flag class has a mixin, and if so if the object being checked for is of that same type. Dutcho, my apologies. Looks like I did not fully understand how __contains__ is supposed to work and a TypeError
