Allow for more quiz styling

Hello, after working to customize the way quiz questions and results are templated and styled, I would strongly suggest using theme functions to render the final output of the quiz elements. Especially the results pages are hard to theme.

For example, I have overridden the QuizResultAnswerViewBuilder alterBuild() method and, along with some custom logic, returned this at the very end:

    $build['quiz_result_answer'] = [
      '#theme' => 'MYMODULE_quiz_result_answer',
      '#question' => $question_render,
      '#rows' => $rows,
      '#result_meta' => $result_meta,
    ];

    return $build;
  }

Even simpler, some of the controller methods I just wrapped the output in a theme function:

namespace Drupal\MYMODULE_quiz_customizations\Controller;

use Drupal\quiz\Controller\QuizQuestionController as OriginalQuizQuestionController;
use Drupal\quiz\Entity\Quiz;

class QuizQuestionController extends OriginalQuizQuestionController {

  /**
   * {@inheritdoc}
   */
  function feedback(Quiz $quiz, $question_number) {
    $page = parent::feedback($quiz, $question_number);
    return [
      '#theme' => 'MYMODULE_quiz_question_feedback',
      '#content' => $page['body'],
    ];
  }

  /**
   * {@inheritdoc}
   */
  function take(Quiz $quiz, $question_number) {
    $content = parent::take($quiz, $question_number);
    return [
       '#theme' => 'MYMODULE_quiz_question_take',
       '#content' => $content,
    ];
  }

}

This let me add wrappers around the actual question component in a template file.

I can upload a patch if you would like to see more specifically what I'm proposing.

100% lets try and land this for 7.0.x release
