Message:

When setting the poster image for a video shortcode, set that image as the featured image for that attachment (if found) in the background. This AJAX functionality could be used for audio as well.

Introduces attachment_url_to_postid() to attempt to turn URLs into post IDs.

Fixes #27891.
