This reverts commit
848594a8fd844879fede9f8663d279b1bfac8253. The initial CL was reverted because the Android GN build was failing to compile. GN files have been added.
Refactor get_salient_image_url.js to use the DocumentImageExtractor.
Move get_salient_image_url.js into components so it accessible for
iOS as well.
