First pass at integrating featured images with the new media workflow.

Updates the featured image when the publish/update button is clicked (rather than instantly). Uses the existing post_thumbnail_meta_box() function. Does not remove the old featured image meta box JS, ajax handler, or CSS.

see #21776, #21390.
