Use a GOnce to make sure we only warn about notifications not being
supported on Windows once, rather than on each attempted notification.

This adds a null notification backend implementation for win32, purely
to avoid crashes due to a missing backend when applications use
GNotification. This backend does nothing except print a warning when a
notification is supposed to be emitted.
In future, it can be expanded to use win32 API to present toaster
notifications appropriately.
