gtk3 a11y: Drop obsolete handling when notifying child removal

This special handling with the comment saying

/*
* the atk-bridge GTK+ module gets back to the event source to ref the child just
* vanishing, so we keep this reference because the semantic on OOo side is different.
*/

was added long ago, in

Ensure the child data is added to children-changed events properly.

where ATK already only calls `atk_object_ref_accessible_child`
for the "children-changed:add", not the "children-changed:remove"
event, and that is still true today, see [2].

Therefore, drop the special handling.
