Customize: Reject a changeset update when a non-future date is provided and also ensure that a published changeset always gets set to the current date/time. 

* Also moves checks from `customize_save` Ajax handler to the underlying `WP_Customize_Manager::save_changeset_post()` call which plugins may invoke directly.
* Ensures that `customize_save_response` filter is always passed an array, with error code available as `code`.
