Customize: Combine Ajax requests for initial load of available nav menu items into a single request.
When there are many post types registered, prevent Ajax requests from piling up and slamming WordPress with concurrent requests. Props curdin, westonruter. Fixes #36697. Built from https://develop.svn.wordpress.org/trunk@39137 git-svn-id: http://core.svn.wordpress.org/trunk@39077 1a063a9b-81f0-0310-95a4-ce76da25c4cd
