Introduce MenuBar

MenuBar is an ordinary Item. It can be located basically anywhere, but
the idea is to introduce a new ApplicationWindow::menuBar property in a
follow-up commit. Currently the example snippets are using the header
property.

[ChangeLog][Controls][MenuBar] Introduced a MenuBar control.
