 Query: Cache post parent IDs in `posts` group.

 Move the cache of post parent IDs from the dedicated group `post_parents`
 to `posts`. This maintains backward compatibility for clearing all post
 object related data by calling `wp_cache_flush_group( 'posts' )`.

 Post parent IDs are now cached with with the prefix `post_parent:` in the
 `posts` group.

 Follow up to [56763].

 Props spacedmonkey, joemcgill, peterwilsoncc.
 See #59188.
