John Blackbourn 3a9cc4bf11 Posts, Post Types: Introduce a missing private query var that should have been introduced as part of #15459. ...

This private query var allows the hierarchical page query on the Pages listing screen to query for `wp_posts.ID, wp_posts.post_parent` instead of `wp_posts.*`. This introduces large memory and time savings when the site contains a large number of Pages. Combined with the processing time savings introduced in [31730] this makes the Pages listing screen considerably more performant.

Fixes #34982
