Add option to show each language name in its own translation

Please add option to show each language in selection in its own translation of that language name. For example:

• English
• Русский
• Français
• Deutsch
• Español

Quick and dirty code i used to replace current "Language Native Name" with this functionality in LaguageDropdownForm.php:

        case LANGDROPDOWN_DISPLAY_NATIVE:
          $native_language = \Drupal::languageManager()->getNativeLanguages()[$lang_code];
          $native_language_translated = $this->t($native_language->getName(), [], ['langcode' => $lang_code]);
          $options += [$lang_code => $native_language_translated];
          break;

Thanks
