Type hints on varargs and kwargs that take anything should be Any. (#11950)

Type hinting `*args` as `List[Any]` means that each positional argument
should be a list. Type hinting `**kwargs` as `Dict[str, Any]` means that
each keyword argument should be a dict of strings.

This is almost never what we actually wanted, and doesn't seem to be
what we want in any of the cases I'm replacing here.
