Instead of storing the function names (in a badly named Vector<String>) and source ranges separately, consolidate them into a new struct: TracebackFrame. This makes it both easier to use now and easier to extend in the future. Unlike before we now keep each call frame's current node source range in the traceback frame next to the function name, meaning we can display line and column numbers outside of the VM and after the call stack is emptied.
