Add a QSplashScreen constructor taking a QScreen

The constructor taking a QWidget is needed for specifying the screen
where the splash screen should be displayed.

Add a new constructor for specifying the target screen for the splash screen
directly, instead of "extracting" the screen information from a widget.
This removes the need for using the deprecated QDesktopWidget.

Deprecate the constructor taking a QWidget.
