#30277: Split up Customizer JS into separate files and remove self-booting
jQuery.ready call

----------------------------+-------------------------
 The `customize-controls.js` file is huge and is named incorrectly now with
 #28709 and the fleshed-out models for Panels and Sections. The file should
 be broken up into `customize-sections.js`, `customize-panels.js`, and
 `customize-utils.js`. The last of which should include the private
 function exposed as public methods off of `wp.customize.utils`. This may
 also include the `wp.customize.init()` mentioned in #29071. We need to
 stop booting the Customizer inside of these JS libraries with a direct
 `jQuery.ready` call, and instead let the including page invoke that. This
 is critical for code reusability and for unit testing. For instance, the
 `customize.php` page could do in the footer:

 {{{#!php
 <script>
 jQuery(function () {
     wp.customize.init( _wpCustomizeSettings );
 });
 </script>
 }}}

 For `wp.customize.utils`, see existing patch at: https://github.com/xwp
