use qOverload<T>(fptr) instead of QOverload<T>::of(fptr)
Now that we are using C++17 we can use qOverload<T> (function_pointer)
instead of QOverload<T...>::of (function_pointer)
Affected files: ButtonGroup.cc, Container.cc, Figure.cc,
PopupMenuControl.cc, command-widget.cc, documentation-bookmarks.cc,
file-editor-tab.cc, file-editor.cc, main-window.cc, octave-qobject.cc,
