function content_taxonomy_allowed_values_opt_groups in Content Taxonomy 7

Helper function for generating opt groups.

Similar to content_taxonomy_allowed_values(), but unfortunately we cannot directly change content_taxonomy_allowed_values() as it only has the field variable and opt groups are settings on the instance level. Still, this is not a big performance issue, as taxonomy_get_tree statically caches some data.
