* Incorporates code from the Customize Snapshots and Customize Posts feature plugins.
* Adds a new Publish Settings section for managing the changeset status, scheduled date, and frontend preview link.
* Updates Publish button to reflect the status selected in the Publish Settings (including Save Draft and Schedule).
* Deactivates the Themes section when a non-publish status selected, and deactivates the Publish Settings section when previewing a theme switch.
* Introduces an `outer` section type (`wp.customize.OuterSection` in JS) for the Publish Settings section to use and for available widgets and available nav menu panels to use in the future. These sections can be expanded while other sections are expanded.
* Introduces `WP_Customize_Date_Time_Control` in PHP and `wp.customize.DateTimeControl` in JS for managing a date/time value.
* Keeps track of scheduled time and proactively publish from the client when the time arrives, as opposed to waiting for WP Cron.
* Auto-publishes a scheduled changeset when attempting to access one that missed its schedule.
* Starts a new changeset if attempting to save a changeset that was previously publish.
* Adds `force` arg to `requestChangesetUpdate()` to force an update request even when there are no pending changes.
* Adds utils methods for `getCurrentTimestamp` and `getRemainingTime`.
* Adds new state values for `selectedChangesetStatus`, `changesetDate`, `selectedChangesetDate`.
* Fixes logic for when to short-circuit check to close Customizer when there are unsaved changes.
* Adds getter methods for `autosaved` and `branching` parameters, with the latter applying the `customize_changeset_branching` filter.
* Call to `establish_loaded_changeset` on the fly when `changeset_uuid()` is called if no changeset UUID was specififed.
* De-duplicates logic for dismissing auto-draft changesets.
* Includes unit tests.

When a setting is invalid, not only will it be blocked from being saved but all other settings will be blocked as well. This ensures that Customizer saves aren't partial but are more transactional. User will be displayed the error in a notification so that they can fix and re-attempt saving.
PHP changes:
* Introduces `WP_Customize_Setting::validate()`, `WP_Customize_Setting::$validate_callback`, and the `customize_validate_{$setting_id}` filter.
* Introduces `WP_Customize_Manager::validate_setting_values()` to do validation (and sanitization) for the setting values supplied, returning a list of `WP_Error` instances for invalid settings.
* Attempting to save settings that are invalid will result in the save being blocked entirely, with the errors being sent in the `customize_save_response`. Modifies `WP_Customize_Manager::save()` to check all settings for validity issues prior to calling their `save` methods.
* Introduces `WP_Customize_Setting::json()` for parity with the other Customizer classes. This includes exporting of the `type`.
* Modifies `WP_Customize_Manager::post_value()` to apply `validate` after `sanitize`, and if validation fails, to return the `$default`.
* Introduces `customize_save_validation_before` action which fires right before the validation checks are made prior to saving.
JS changes:
* Introduces `wp.customize.Notification` in JS which to represent `WP_Error` instances returned from the server when setting validation fails.
* Introduces `wp.customize.Setting.prototype.notifications`.
* Introduces `wp.customize.Control.prototype.notifications`, which are synced with a control's settings' notifications.
* Introduces `wp.customize.Control.prototype.renderNotifications()` to re-render a control's notifications in its notification area. This is called automatically when the notifications collection changes.
* Introduces `wp.customize.settingConstructor`, allowing custom setting types to be used in the same way that custom controls, panels, and sections can be made.
* Injects a notification area into existing controls which is populated in response to the control's `notifications` collection changing. A custom control can customize the placement of the notification area by overriding the new `getNotificationsContainerElement` method.
* When a save fails due to setting invalidity, the invalidity errors will be added to the settings to then populate in the controls' notification areas, and the first such invalid control will be focused.

Introduces `WP_Customize_Manager::get_previewable_devices()` with a `customize_previewable_devices` filter to change the default device and which devices are available for previewing. This is a feature that was first pioneered on WordPress.com.

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.
