Featured Image Block: Add option to use first image of post

[cuemarie]

What

Add the option to use the first image of a post, if no featured image is set for that post.

Why

This is particularly useful for people replacing classic themes with block themes. Many old posts don't have featured images, and it's a lot of work to go back to them and add them all. This allows theme builders to use the post featured image block in a query block and have more confidence that an image will show.
