winrt: handle PrelaunchActivated property to pass certification
Windows 10 requires apps to handle the PrelaunchActivated property. This enables a faster startup by launching an app and immediately suspending it. This happens by the system and at the time the user launches the app no library loading or initialization is required. By default we opt-out of this and return early. The reason is that we cannot know the type of application written in Qt and whether it breaks the guidelines by using prelaunch.
