Daryl Koopersmith f42b826898 Media: Show an inline uploader when the media library is empty.
Merges most of `wp.media.controller.Upload` into `wp.media.controller.Library`, so we always create an inline uploader instead of an attachments browser if the state's `library` is empty.

props rzen, fixes #22323, see #21390.
