 {{{
 #!CommitTicketReference repository="" revision="41390"
 Customize: Add notifications API to sections and panels.

 * Adds a `notifications` property to instances of `wp.customize.Panel` and
 `wp.customize.Section`.
 * Adds a `setupNotifications()` method to `Panel`, `Section`, and
 `Control`.
 * Adds a `getNotificationsContainerElement()` method to the `Panel` and
 `Section` classes, like `Control` has.
 * Replace hard-coded notification in header media section with a
 notification.
 * Limit rendering notifications to panels and sections that are expanded,
 and to controls that have an expanded section.

 See #34893, #35210, #38778.
 Fixes #38794.
