Support multivalue checkboxes attribute elements
Fixed
After Drupal 10.3.5 upgrade (basically any version after #3427177 📌 Replace calls to ::expectError*() from Drupal\Tests\Core\Render\ElementTest Fixed is committed to Drupal Core), it throws fatal error for any pages with menu item having multiple checkboxes type data:
InvalidArgumentException: "role_1" is an invalid render array key. Value should be an array but got a string. in Drupal\Core\Render\Element::children() (line 97 of core/lib/Drupal/Core/Render/Element.php).
It still supports single value checkbox, single select and radios. Seems like multi-value fields are affected.

It seems a better way to store multi-value data as JSON encoded string. Raised merge request according to that.
