LibJS: Add side-effect-free version of Value::to_string()
There are now two API's on Value: - Value::to_string(Interpreter&) -- may throw. - Value::to_string_without_side_effects() -- will never throw. These are some pretty big sweeping changes, so it's possible that I did some part the wrong way. We'll work it out as we go. :^) Fixes #2123.
