Message:

Customize: Fix reliability of just-in-time publishing for changesets that miss their schedule when visiting customize.php.

When just doing wp_publish_post() for the changeset from customize.php, any option-based settings will fail to get saved because WP_Customize_Manager would have already been loaded with settings_previewed, resulting in update_option() calls being short-circuited. So an admin-ajax request to customize_save is used to work around this.

Props westonruter, jeremyfelt, dlh for testing, LittleBigThing for testing.
Amends [41626].
See #28721, #39221.
Fixes #42457 for 4.9.
