Sona Kurazyan 9cc040a806 Prepare for deprecating the QDesktopWidget 
QDesktopWidget is marked as obsolete in docs, but it is not yet
completely deprecated, some of its methods are still in use.

Replace uses of the following methods marked as obsolete:
- QDesktopWidget::screenNumber(QWidget*) -> QWidget::screen()
- QDesktopWidget::screenGeometry(QWidget*) -> QWidget::screen()->geometry()
- QDesktopWidget::availableGeometry(QWidget*) -> QWidget::screen()->availableGeometry()

Task-number: QTBUG-76491
