LibGUI, WindowServer: Greatly simplify menubar logic

Browse source 
Currently, any number of menubars can be plugged in and out of a window.
This is unnecessary complexity, since we only need one menubar on a
window. This commit removes most of the logic for dynamically attaching
and detaching menubars and makes one menubar always available. The
menubar is only considered existent if it has at least a single menu in
it (in other words, an empty menubar will not be shown).

This commit additionally fixes a bug wherein menus added after a menubar
has been attached would not have their rects properly setup, and would
therefore appear glitched out on the top left corner of the menubar.
