Comment:

 In [changeset:"54685" 54685]:
 {{{
 #!CommitTicketReference repository="" revision="54685"
 Query: Move cache key generation to its own method.

 Introduce `WP_Query::generate_cache_key()` for generating the cache key
 used by the main database query.

 This removes the need for a filter to test that cache keys do not include
 the WPDB placeholder causing unreachable cache keys. The tests now call
 `WP_Query::generate_cache_key()` directly.

 The filter `wp_query_cache_key` is removed as a hard deprecation. The
 filter was not included in a stable release.

 Follow up to [54634].

 Fixes #56802.
