[gtk] Make gtk_widget_activate_action better

[Matthias Clasen <matthiasc src gnome org>]

commit 3acc0144999ab1e25bc6408fb3d72c9b05822b61
Author: Matthias Clasen <mclasen redhat com>

    Make gtk_widget_activate_action better
    
    As a convenience API, this should be easy to use,
    so don't expect callers to manually create a
    variant, do it for them.
    
    Update all callers.
