Message:

Media: Use featured image if available for attachment as preview instead of icon.

When rendering a list of attachments in WP_Media_List_Table class, none image attachments, show a generic icon. However, attachment types like audio and video support adding a featured image. For attachments that have featured images, us this image instead of the icon. This featured image is a better preview than a generic icon.

Props spacedmonkey, samful, johnbillion, JavierCasares, seanchayes, antpb, cadic, JeffPaul.
Fixes #49852.
