clutter: Use va_marshaller for Actor signals

Browse source 
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).
