Add ClutterFrame arguments to after-paint signal handlers

The ClutterFrame argument was added to several signals with mutter commit
08b0e563d4d0088e19d24f3199626a2d27349d09. We have a bunch of after-paint
handlers in gnome-shell too, and updating those was apparently forgotten,
introducing subtle memory corruption that was luckily easy to track down by
running gnome-shell with ASAN enabled. Let's fix that and add the additional
argument to all the signal handlers.
