Message:

REST API: Add support for filename search in media endpoint.

In [38625], the functionality to search for attachments by filename was added via the posts_clauses filter and the _filter_query_attachment_filenames() function. This moves _filter_query_attachment_filenames() from wp-admin/includes/post.php to wp-includes/post.php so that it can be applied in the same manner in the REST API media endpoint.

Merge of [39598] to the 4.7 branch.

Props jblz, tyxla.
Fixes #39092.
