 {{{
 #!CommitTicketReference repository="" revision="53941"
 Query: Cache post ID database query within `WP_Query`.

 Add object caching to the first database query in `WP_Query`, ie the
 database query for post IDs that match the desired result. Randomly
 ordered queries remain uncached as they are not intended to return
 consistent results.

 Caching of ID queries is enabled by default, per the post object, term and
 meta caches.

 Props spacedmonkey, aaroncampbell, batmoo, chriscct7, costdev, dd32,
 drewapicture, johnbillion, mukesh27, nacin, ocean90, peterwilsoncc, ryan,
 scribu, sergeybiryukov, tillkruss.
 Fixes #22176.
