Carlos Garnacho fb04dafb0b st: Use g_signal_handler_disconnect() to disconnect from StTheme
With a high enough amount of actors, there may be enough theme nodes and
signal connections on StTheme::custom-stylesheets-changed that
g_signal_handlers_disconnect_by*() on dispose becomes expensive, this may
become a surprisingly hot spot in StWidget::style-changed.

Keep the handler ID around and use g_signal_handler_disconnect() to avoid
linear lookups for the matching func/data.
