needs to be the only perceivable content in the page for users of assistive
technologies. It looks like a modal but it's not exactly an ARIA dialog, not an
ARIA alert either, and needs some special treatment.
- constrains tabbing within the modal
- uses `wp.a11y.speak()` to make screen readers announce the modal message
- hides all the other page content from assistive technologies using `aria-hidden="true"`

* Introduce `WP_Customize_Themes_Section::$filter_type`, which has built-in functionality for `local` and `remote` filtering. When this set to `local`, all themes are assumed to be loaded from Ajax when the section is first loaded, and subsequent searching/filtering is applied to the loaded collection of themes within the section. This is how the core "Installed" section behaves - third-party sources with limited numbers of themes may consider leveraging this implementation. When this is set to `remote`, searching and filtering always triggers a new remote query via Ajax. The core "WordPress.org" section uses this approach, as it has over 5000 themes to search.
* Refactor `filterSearch()` to accept a raw term string as input. This enables a feature filter to be used on a section where `filter_type` is `local`.
* Refactor `filter()` on a theme control to check for an array of terms. Also sort the results by the number of matches. Rather than searching for an exact match, this will now search for each word in a search distinctly, allowing things like tags to rank in search results more accurately.
* Split `loadControls()` into two functions for themes section JS: `loadThemes()` to initiate and manage an Ajax request and `loadControls()` to create theme controls based on the results of the Ajax call. If third-party sections need to change the way controls are loaded, such as by using a custom control subclass of `WP_Customize_Theme_Control`, this allows them to use the core logic for managing the Ajax call and only override the actual control-creation process.
* Introduce `customize_load_themes` filter to facilitate loading themes from third-party sources (or modifying the results of the core sections).
* Bring significant improvements to the installed themes search filter.

It doesn't look like `wp_register_sidebar_widget()` ever used a global named `$wp_register_widget_defaults`. It does however make use of `$wp_registered_widget_controls` now.

* Open the door for future browser history feature in #28536, which is currently not feasible when customize-loader is used.
* Remove customizer-loader from being used on admin screens for Dashboard, Themes, non-shiny theme install/update.
* Keep the customize-loader functionality available for plugins, for the time being. It may become deprecated.
* Ensure `return` param in customizer links in Themes screen update to reflect `search` updated by `pushState`.
* Persist `return` when reloading Customizer due to theme switch, autosave restoration, or changeset trashing.
* Use `location.replace()` instead of changing `location.href` when trashing.
* Hide theme browser while Themes screen is loading when there is a `search` to prevent flash of unfiltered themes.
* Use throttling instead of debouncing when searching themes to ensure that screen is updated immediately on page load.
* Fix encoding and decoding of `search` param between URL and search field.
* Add support for dismissing autosaves when closing customize-loader, when it is used by plugins.
* Skip sending changeset UUID to customize-loader for population in browser location if changeset branching is not enabled.
