 Prime users cache in WP_Query and post REST API controller.

 For a call to `WP_Query` or a post REST API request that contains posts
 from multiple authors, call the `cache_users` function, to ensure that all
 user data for post authors is primed in
 a single database query. This results in far fewer database queries on
 multiple author sites.

 Props spacedmonkey, timothyblynjacobs, peterwilsoncc.
 Fixes #55716.
