Processes attachments of HTML responses.
This class is used by the rendering service to process the #attached part of the render array, for HTML responses.
To render attachments to HTML for testing without a controller, use the 'bare_html_page_renderer' service to generate a Drupal\Core\Render\HtmlResponse object. Then use its getContent(), getStatusCode(), and/or the headers property to access the result.
