Add theme hook suggestions

[ademarco]

So I put together something like that:

/**
 * Implements hook_ui_patterns_suggestions_alter().
 */
function ui_patterns_ui_patterns_suggestions_alter(array &$suggestions, array $variables, PatternContext $context) {
  if ($context->isOfType('entity')) {
    $hook = $variables['theme_hook_original'];
    $entity_type = $context->getProperty('entity_type');
    $bundle = $context->getProperty('bundle');
    $view_mode = $context->getProperty('view_mode');

    $suggestions[] = $hook . '__entity__' . $entity_type;
    $suggestions[] = $hook . '__entity__' . $entity_type . '__' . $bundle;
    $suggestions[] = $hook . '__entity__' . $entity_type . '__' . $view_mode;
    $suggestions[] = $hook . '__entity__' . $entity_type . '__' . $bundle . '__' . $view_mode;
  }
}

this produces the following suggestions:

<!-- THEME DEBUG -->
<!-- THEME HOOK: 'pattern__button' -->
<!-- FILE NAME SUGGESTIONS:
   x pattern--button.html.twig
   * pattern--button--entity--node--article--full.html.twig
   * pattern--button--entity--node--full.html.twig
   * pattern--button--entity--node--article.html.twig
   * pattern--button--entity--node.html.twig
   * pattern.html.twig
-->
<!-- BEGIN OUTPUT from 'themes/contrib/ui_patterns_test_theme/templates/patterns/button/pattern--button.html.twig' -->
