Subject: [PATCH] Allow pseudo post types `attachment:audio` and
 `attachment:video` to get the media modal on Edit Media when they support
 featured images.

Introduces `post_supports_thumbnails( $post )` and `theme_supports_thumbnails( $post )` to cut down on duplicated code everytime this needs to be checked. There will be more cases forthcoming.

See #26631.
