Implement alertion state for windows.
Add QWindow::alert() and QPlatformWindow::setAlertState().
Add logic to clear alertion state when the window becomes
active. The platform plugins then only need to implement a setter
and a cheap getter and need not handle activation.
Prototypically implement X11 and Windows.
