Subject: [PATCH] REST API: Add the `supports` property to the Post Type
 response object.

Includes a new `supports` property in the response object and schema for the `/types` endpoints for users with the `edit_posts` capability for the given post type. The `supports` property returns an object of the features the given post type *supports*.

Props timmydcrawford, tyxla.
Fixes #39033.
