f861754016 Customizer: Better experience for widget filtering in desktop and iOS Safari.
Previously, the search field did not appear at all in desktop Safari, and the auto-focus keyboard fly-up in iOS rendered widget adding frustrating at best.

props dsmart, ocean90.
fixes #31987.

6d2c70aa0d Customizer: Refresh nonces when a session expires and the user logs in again.
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.

cde6d602ea Widget Customizer: Improve plugin compatibility.
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."
