Posts: Introduce `WP_Post_Type` and use it in `register_post_type()` and `unregister_post_type()`. 

This changes the global `$wp_post_types` to an array of `WP_Post_Type` objects. `WP_Post_Type` includes methods to handle post type supports, rewrite rules, meta boxes, hooks, and taxonomies.
Each post type argument becomes a property of `WP_Post_Type`.

Props swissspidy, flixos90.
Fixes #36217.
