Media library integration does not work well for fields that accept multiple values

Started with the cardinality / max files. Actually inserting the newly uploaded files into the media library is still to be done.

      $resup_file_ids = explode(',', $input['resup']);
      $resup_file_id = reset($resup_file_ids);

The above piece of code from \Drupal\file_resup\Form\FileFormAlterBase::fileValue() is the reason that the widget does not insert multiple images, even if multiple images are upload in one go.

The MR fixes both the cardinality / max files and the insertion of multiple images at once.

A patch of the MR is attached to this comment.
