When calling QWidgetWindowPrivate::setFocusToTarget with Prev or Next target parameter, we were just setting focus to the next/prevInFocusChain() of the window's focusWidget(). This will bypass focus proxies and focus policies of the widget, which is wrong as it can end up giving eg: tab focus to a widget that does not have such focus policy. To fix, we should instead call QWidget::focusNextPrevChild which determines the right next/prev in the TAB focus chain. As this is a protected member of QWidget, implement a "wrapper" for it in QWidgetWindow which is a friend class of QWidget.
