replace use of depreciated QDesktopWidget in GUI
* gui-utils.cc: include QApplication, QRect and QScreen;
(get_screen_geometry): return QRect with geometry of primary screen;
(adjust_to_screen): adjust given QRect to be completely on the screen
that contains the largest part of the QRect, use a default geometry if
no part is on an available screen
* gui-utils.h: include QRect;
new function get_screen_geometry and adjust_to_screen
* community-news.cc: do not include QDesktopWidget, but gui-utils.h;
(get_screen_geometry); move function to gui-utils.cc;
* community-news.h: move get_screen_geometry to gui-utils.h
* find-dialog.cc: do not include QDesktopWidget, but gui-utils.h;
(restore_settings): use new function adjust_to_screen
* main-window.cc: do not include QDesktopWidget, but gui-utils.h;
(get_screen_geometry: move function to gui-utils.cc
* main-window.h: move function get_screen_geometry to gui.utils.h;
* octave-dock-widget.cc: do not include QDesktopWidget, but gui-utils.h
QScreen and QWindow;
(handle_settings): use adjust_to_screen and QGuiApplication->primaryScreen
* release-notes.cc: do not include QDesktopWidget, but gui-utils.h
and QScreen;
(get_screen_geometry): move to gui-utils.cc;
* release-notes.h: move get:screen_geometry to gui-utils.h
* terminal-dock-widget.cc: do not include QDesktopWidget but QScreen;
(terminal_dock_widget): use QGuiApplication->primaryScreen instead
of QDesktopWidget->screenGeometry
* welcome-wizard.cc: remove include of QDesktopWidget
