Subject: [PATCH] Editor: In `_WP_Editors::wp_link_query`, allow filtering
 empty results.

Previously, it was not possible to hook into the `wp_link_query` filter to add custom entries when the
query returned no posts.

Props mitraval192, msebel.
Fixes #41825.

Built from https://develop.svn.wordpress.org/trunk@41346
