[mutter/wip/nielsdg/cleanup-clutter-marshal: 2/2] clutter: Use va_marshaller for Actor signals

    clutter: Use va_marshaller for Actor signals
    
    If possible, GLib will try to use the va_marshaller to pass the signal
    arguments, rather than unboxing into and out of a `GValue`. This is much
    more performant and especially good for often-thrown signals.
    
    The original bug even mentions Clutter performance issues as a drive to
    implement the va_marshaller in GLib (see
    https://bugzilla.gnome.org/show_bug.cgi?id=661140).
