a11y: Use ATK macros and clean up/2 - GtkSpinner
ATK provides macros to the same effect as G_DEFINE_TYPE; using these macros has the advantage of removing tons of duplicated code and reducing the maintainership burden. The widgets with inline accessibility implementation should switch to these macros, and clean up the code. https://bugzilla.gnome.org/show_bug.cgi?id=636060
