CodeWindow: Hide GetMenuBar()

This eliminates public usage of the GetMenuBar() function in CodeWindow.
The benefit of this is it also gets rid of the need to perform direct
access across the config dialog and the main frame. It also gets rid of
the use of the main_frame global.

GetMenuBar() will be removed entirely from CodeWindow in a follow-up that
also removes any related remnants of code made obsolete with its removal.
