typing: add type hints to pycompat.maplist()
The typeshed hints define 5 overloads with an increasing number of parameters on
the passed function, and then a catchall that ignores the argument list on the
passed function and allows an `*iterators` arg. All of our uses are fulfilled
by the 1 function + 1 iterable overload, but add the second overload as a hint
in case it's needed in the future.
