Handling sets in cmp for dict view types #3298
Description
Currently, sets are not handled in comparisons with dict views:
In Python:
>>> d = {1: 2}
>>> d.keys() == set([1])
Truewhile in RustPython:
>>>>> d = {1: 2}
>>>>> d.keys() == set([1])
FalseIn CPython, the corresponding implementation (dictview_richcompare) calls another function that iterates through the view and continuously calls __contains__ on the other object (see all_contained_in function).

Hi. Is there anyone working on this issue?
If not, I'd like to work on it.

@zetwhite no one else has requested so I'm assuming that no. Go for it!

I reviewed this issue but this is not a good first issue.
