In [53941], the addition of query caching to `WP_Query` brought about an unintended issue when querying for fields equal to id=>parent. Specifically, on websites with object caching enabled and a substantial number of pages, the second run of this query triggered the `_prime_post_caches` function for id=>parent. This led to the unnecessary priming of post, meta, and term caches, even when only id and parent information were requested. This commit addresses this issue by introducing a new function, `_prime_post_parents_caches`, which primes a dedicated cache for post parents. This cache is primed during the initial query execution. Subsequently, the `wp_cache_get_multiple` function is employed to retrieve all post parent data in a single object cache request, optimizing performance. Additionally, this commit extends the coverage of existing unit tests to ensure the reliability of the changes. Props kevinfodness, joemcgill, peterwilsoncc, LinSoftware, thekt12, spacedmonkey.
