clutter-backend-egl: Chain up in dispose before destroying the context

Browse Source 
clutter_backend_egl_dispose now chains up before disposing its own
resources so that ClutterBackendX11 will destroy all of the stages
before we destroy the egl context. Otherwise the actors may try to
make GL calls during destruction which causes a crash.
