typing: add more type hints to the errors module

These were found by looking for `Any` types in the generated `*.pyi` file after
running the tests.  There are some more complicated types that I'm not sure of,
and am leaving untyped.  I also can't figure out how to get `self.hint` to be
anything other than `Any` in most classes.
