Comments: Use wp_cache_get_multiple in WP_Comment_Query.

In the `fill_descendants` method in `WP_Comment_Query`, there is a loop the calls `wp_cache_get` to get `child comments. Instead of getting one key at a time, use `wp_cache_get_multiple` and get all keys at once.

Props spacedmonkey, tillkruess, mukesh27.
Fixes #57803.
