The Menu Customizer feature includes a performance technique whereby the controls for nav menu items are only embedded into the DOM once the containing menu section is expanded. This commit implements the same DOM deferral for widgets but goes a step further than just embedding the controls once the widget area's Customizer section is expanded: it also defers the embedding of the widget control's form until the widget is expanded, at which point the `widget-added` event also fires to allow any additional widget initialization to be done. The deferred DOM embedding can speed up initial load time by 10x or more. This DOM deferral also yields a reduction in overall memory usage in the browser process.
Includes changes to `wp_widget_control()` to facilitate separating out the widget form from the surrounding accordion container; also includes unit tests for this previously-untested function. Also included are initial QUnit tests (finally) for widgets in the Customizer.
Fixes#33901.

* Ensure that a Custom Menu widget selecting a newly-inserted menu gets updated to use the new menu ID upon Save & Publish.
* Dynamically update the visibility of the Custom Menu widget's "no menus" message when the number of menus changes between 0 and 1+.
* Send all dirty Customized settings in `update-widget` Ajax request and `preview()` them so that the widget update/form callbacks have access to any data dependencies in the current Customizer session (such as newly created unsaved menus).
* Update link in Custom Menu widget to point to Menus panel as opposed to Menus admin page, when in the Customizer.
* Fix an issue with extra space at top immediately after creating new menu.
* Fix doubled `update-widget` Ajax requests when changing select dropdown; prevent initial from being aborted.
* Add missing `wp_get_nav_menus()` hooks to preview Customizer updates/inserts for `nav_menu` settings; includes tests.
* Update `wp_get_nav_menu_object()` to allow a menu object to be passed in (and thus passed through).

This was broken since 4.0 and the introduction of user session tokens. The nonces are now tied to session tokens as opposed to user IDs, and thus they change with each re-login.
Custom nonces can be added through the `customize_refresh_nonces` filter. On a successful refresh request the JavaScript API will trigger a `nonce-refresh` event. See widget's update nonce as an example.

Control can indicate its active state by a subclass overriding the 'active_callback' method, by supplying a callable 'active_callback' argument into the control's constructor, or by filtering 'customize_control_active'.

Create a panel via `$GLOBALS['wp_customize']->add_panel( $panel_id, $args )` and use `$panel_id` for the `panel` argument in `$GLOBALS['wp_customize']->add_section( $section_id, $args )`. That's it.
As an example all widget area sections are now summarized into one panel. Feedback appreciated.

Some plugins are using custom scripts and styles for there widgets. These are available on the Widgets screens, but not in the Customizer yet.
Scripts and styles can be enqueued via:
* `admin_enqueue_scripts`
* `admin_print_scripts` and `admin_print_scripts-widgets.php`
* `admin_print_styles` and `admin_print_styles-widgets.php`
* `admin_print_footer_scripts` and `admin_footer-widgets.php`
All this hooks are now called in the Customizer too.
Previously we have add the `#widgets-right` ID to a container div via jQuery. Remember: `#widgets-right` exists on the Widgets screen and is used by many plugins to do event delegation from that element.
But since our script files are loaded in the footer, the JavaScript way is a bit late for some plugins.
We have decided to add a `div#widgets-right` container element to customizer. "Less hacky hack."
