Comment:

 Any fields added using the backward compatible filter
 `attachment_fields_to_edit` are already rendered in the new media modal
 and can be saved by hooking into `attachment_field_to_save`, which is
 fired by `wp_ajax_save_attachment_compat()`. These fields can also be
 registered to work on the new "Edit Media" screens, so I'm not sure a hook
 is really necessary here.

 Here's how something similar would be done:

 {{{
 function attachment_url_field_23148( $form_fields, $post ) {
         $form_fields['attachment_url_23148'] = array(
                 'label'        => 'Link',
                 'input'        => 'text',
                 'value'        => get_post_meta( $post->ID,
 'attachment_url_23148', true ),
                 'show_in_edit' => false,
         );

         return $form_fields;
 }
 add_filter( 'attachment_fields_to_edit', 'attachment_url_field_23148', 10,
 2 );

 function save_attachment_url_23148( $post, $data ) {
         if ( isset( $data['attachment_url_23148'] ) ) {
                 update_post_meta( $post['ID'], 'attachment_url_23148',
 esc_url_raw( $data['attachment_url_23148'] ) );
         }

         return $post;
 }
 add_filter( 'attachment_fields_to_save', 'save_attachment_url_23148', 10,
 2 );
 }}}
