     * Processes the attachments of a response that has attachments.
     *
     * Libraries, JavaScript settings, feeds, HTML <head> tags, HTML <head> links,
     * HTTP headers, and the HTTP status code are attached to render arrays using
     * the #attached property. The #attached property is an associative array,
     * where the keys are the attachment types and the values are the attached
     * data. For example:
     *
     * @code
     * $build['#attached']['library'][] = [
     *   'library' => ['core/jquery']
     * ];
     * $build['#attached']['http_header'] = [
     *   ['Content-Type', 'application/rss+xml; charset=utf-8'],
     * ];
     * @endcode
     *
     * The available keys are:
     * - 'library' (asset libraries)
     * - 'drupalSettings' (JavaScript settings)
     * - 'feed' (RSS feeds)
     * - 'html_head' (tags in HTML <head>)
     * - 'html_head_link' (<link> tags in HTML <head>)
     * - 'http_header' (HTTP headers and status code)
     *
     * Placeholders need to be rendered first in order to have all attachments
     * available for processing. For an example, see
     * \Drupal\Core\Render\HtmlResponseAttachmentsProcessor::renderPlaceholders()
     *
     * @param \Drupal\Core\Render\AttachmentsInterface $response
     *   The response to process.
     *
     * @return \Drupal\Core\Render\AttachmentsInterface
     *   The processed response, with the attachments updated to reflect their
     *   final values.
     *
     * @throws \InvalidArgumentException
     *   Thrown when the $response parameter is not the type of response object
     *   the processor expects.
