Procedural function twig_without() is deprecated

Summary

The Drupal specific twig filter function without has been moved from being implemented by the procedural twig_without() function to the without() method in \Drupal\Core\Template\TwigExtension.

Usage of the without filter in twig templates is unaffected, however the twig_without function is deprecated and will be removed prior to 9.0.0.

Before

  $filtered_element = twig_without($element, 'key_to_remove', 'key_to_remove_n');

After

  /** @var \Drupal\Core\Template\TwigExtension $extension */
  $extension = \Drupal::service('twig.extension');

  $filtered_element = $extension->without($element, 'key_to_remove', 'key_to_remove_n');
