stage: Add :key-focus property

ClutterStage has both set_key_focus() and get_key_focus() methods, but
there is no :key-focus property. This means that it is not possible to
get notifications when the key-focus has changes except by connecting to
both the ::key-focus-in and ::key-focus-out signals and do additional
bookkeeping.
