* Introduces `customize-selective-refresh-widgets` theme support feature and adds to themes.
* Introduces `customize_selective_refresh` arg for `WP_Widget::$widget_options` and adds to all core widgets.

* Add `WP_Customize_Widgets::get_selective_refreshable_widgets()` and `WP_Customize_Widgets::is_widget_selective_refreshable()`.
* Fix default `selector` for `Partial` instances.
* Implement and improve Masronry sidebar refresh logic in Twenty Thirteen and Twenty Fourteen, including preservation of initial widget position after refresh.
* Re-initialize ME.js when refreshing `Twenty_Fourteen_Ephemera_Widget`.

e11fd98ec6 Customize: Fix regressions and harden implementation of selective refresh for nav menus.
* Request full refresh if there are nav menu instances that lack partials for a changed setting.
* Restore `WP_Customize_Nav_Menus::$preview_nav_menu_instance_args` and `WP_Customize_Nav_Menus::export_preview_data()` from 4.3, and keeping a tally of all `wp_nav_menu()` calls regardless of whether they can use selective refresh.
* Ensure that all instances of `wp_nav_menu()` are tallied, regardless of whether they are made during the initial preview call or during subsequent partial renderings. Export `nav_menu_instance_args` with each partial rendering response just as they are returned when rendering the preview as a whole.
* Fix issues with Custom Menu widget where nav menu items would fail to render when switching between menus when a menu lacked items to begin with.
* Make sure the fallback behavior is invoked when the partial is no longer associated with a menu.
* Do fallback behavior to refresh preview when all menu items are removed from a menu.

2214f69e43 Customize: Allow controls to be registered without any associated settings.
* 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.

Also includes these related changes:
* Export `oldContainer` and `newContainer` among the `customize-preview-menu-refreshed` event params for themes to be able to more easily re-initialize the DOM elements.
* Improve performance for partial refresh by only sending settings related to the menu being previewed.
* Fix previewing of menu assigned to Custom Menu by exporting a menu `term_id` as opposed to an object, as the former is more stable for comparing in in args hashes.
* Do full refresh of preview when nav menu unassigned so that the layout can be updated.
* Harden conditions for when partial refresh is eligible for a `wp_nav_menu()` instance.

a62cc940ea Customizer: Register controls and settings for nav_menu_locations even when there are no menus yet.
This change ensures that the first menu created can be assigned to a location without first saving and reloading the Customizer.

912b434198 Customizer: Fix saving menus with empty names or names that are already used.
Adds validation for initially-supplied nav menu name, blocking empty names from being supplied. If later an empty name is supplied and the nav menu is saved, the name "(unnamed)" will be supplied instead and supplied back to the client. If a name is supplied for the menu which is currently used by another menu, then the name conflict is resolved by adding a numerical counter similar to how `post_name` conflicts are resolved. Includes unit tests.

Fixes #32760.
