Prime comment meta caches in WP_Comment_Query.

Browse Source 
The new 'update_comment_meta_cache' parameter, which defaults to `true`, can
be used to disable this behavior.

`update_comment_cache()` has been updated to support an `$update_meta_cache`
parameter, which also updates to true; this matches the pattern we use for
priming post caches.

See #16894.
