Send back setting validities with full refreshes and selective refreshes so that invalid settings can have notifications displayed immediately before attempting save, and so that these notifications can be cleared as soon as the input is corrected.
* Splits out JS logic for listing controls into separate methods `wp.customize.Setting.prototype.findControls()` and `wp.customize.findControlsForSettings()`.
* Adds a `setting` property to the `data` on notifications added to controls that are synced from their settings.
* Adds `selective-refresh-setting-validities` message sent from preview to pane.
* Changes `WP_Customize_Manager::validate_setting_values()` to return when settings are valid as well as invalid.
* Adds `WP_Customize_Manager::prepare_setting_validity_for_js()`.
* Add setting validities to data exported to JS in Customizer Preview and in selective refresh responses.

* Eliminates need to click more than one checkbox to have preferences saved.
* Adds debouncing to saving user-selected menu item properties.
* Also removes discrepancies between available nav menu item properties on admin page vs Customizer.

* Removes double `margin-bottom` from all the media controls.
* All media controls now send `{settingId}-attachment-data` messages to the preview when a media setting is updated so that the preview has access to the attachment data.
* Fixes receiving of `attachment-data` message for `custom_logo` which resulted in instant JS-applied preview not working. See #36096.

* Improves parity between partials and controls. A partial or control can be settingless if instantiated with `settings` param as empty array (otherwise, if null, then the partial/control ID is used).
* Eliminate need to create dummy settings that serve no purpose except to place a control in the UI.
* Removes dummy settings for `create_new_menu` and `new_menu_name`.
* Introduces `WP_Customize_Control::$capability` and `WP_Customize_Partial::$capability`, and if set checks them in the respective `check_capabilities()` methods.
* Prevents PHP fatal error from happening when non-existing settings are provided to control: "Call to a member function `check_capabilities()` on a non-object".
* Fixes issue where nav menu items and widgets were no longer working with selective refresh because cap check was failing.

Ensures that intentional backslashes (e.g. "\o/") can be used in:
* Site title
* Site description
* Nav menu name
* Custom Menu widget title
* Tag Cloud widget title
* Text widget body if can't `unfiltered_html`
The latter three are also fixed on the widgets admin page.

Prevents slashes from being added when a user without `unfiltered_html` previews a nav menu item containing an apostrophe or some other slashable character, and prevents the loss of an intentional slash (e.g. "\o/") when saving a nav menu item, regardless of capability.

* Introduce `customize_post_value_set_{$setting_id}` and `customize_post_value_set` actions which are done when `WP_Customize_Manager::set_post_value()` is called.
* Clear the `preview_applied` flag for aggregated multidimensional settings when a post value is set. This ensures the new value is used instead of a previously-cached previewed value.
* Move `$is_preview` property from subclasses to `WP_Customize_Setting` parent class.
* Deferred preview: Ensure that when `preview()` short-circuits due to not being applicable that it will be called again later when the post value is set.
* Populate post value for updated-widget with the (unsanitized) JS-value in `WP_Customize_Widgets::call_widget_update()` so that value will be properly sanitized when accessed in `WP_Customize_Manager::post_value()`.
Includes unit tests with assertions to check the reported issues and validate the fixes.

* Apply `title_save_pre`, `excerpt_save_pre`, and `content_save_pre` filters on a nav menu item's `title`, `attr_title`, and `description` properties respectively. This ensures that arbitrary markup can be supplied if the user has `unfiltered_html` cap, and for these fields to have markup stripped if not.
* Ensure a nav menu item's `post_status` is sanitized as `publish` or `draft` using the same conditions as `wp_update_nav_menu_item()`.
* Align `WP_Customize_Nav_Menu_Item_Setting::sanitize()` behavior for sanitizing `position` to be the same as `wp_update_nav_menu_item()`.
* Also apply `nav_menu_attr_title` and `nav_menu_description` filters in `WP_Customize_Nav_Menu_Item_Setting::value_as_wp_post_nav_menu_item()` to ensure that previewing markup entered into menu item description will preview the same way as when the nav menu item is saved.
* Add unit tests.
