typing: add type hints to mercurial/error.py
The only slightly unusual things here are that `location` is passed to
`ParseError` and both bytes and an int (so this accepts both), and the message
passed `ProgrammingError` is immediately converted to str. Therefore it is
typed as `AnyStr`, because there are a couple of instances that are already
passed as str.
There are a couple of places where bytes are being passed to builtin exceptions
that might need to be converted to str.
