Posts, Post Types: Force unique slugs for draft posts.

Browse Source 
This fixes a behavior where a draft created with the same slug as an existing post would set the existing post to a 404.

`wp_unique_post_slug()` returns the same slug for 'draft' or 'pending' posts, so to ensure that a unique slug is generated, this changeset adds the post data with the 'publish' status to `wp_unique_post_slug()`.

Fixes #52422.
