Registers a finalization notifier which will be called when the
reference count of @closure goes down to 0.
Multiple finalization notifiers on a single closure are invoked in
unspecified order. If a single call to g_closure_unref() results in
the closure being both invalidated and finalized, then the invalidate
notifiers will be run before the finalize notifiers.
