    actor: Change the point of emission of ::destroy
    
    Currently, we're emitting the ClutterActor::destroy at the end of the
    dispose implementation - right before we chain up to the parent
    implementation.
    
    The point of emission makes the ::destroy signal handlers able to just
    use the actor pointer - as the actor state will have been mostly cleared
    by the time application can run. This (undocumented) behaviour severely
    limits the amount of things you can do inside a ::destroy signal
    handler, thus making the ::destroy signal just a weird weak reference,
    instead of a proper way to break application reference cycles.
    
    Given that this change relaxes some of the conditions, this change
    should be safe - obviously, if anything happens, we'll back it out; the
    conformance and interactive tests confirm that, for common patterns of
    usage, this change does not break existing code.
