Implement QSystemTrayIcon for Windows.

Browse Source 
No longer base the implementation on a QWidget which is not
necessary when all that is required is a message window listening
to task-tray messages. Export a service function creating a message
window from the Windows native interface and use that.

Task-number: QTBUG-20978
