Only add the clear_button plugin to TomSelect if the form element is not required

we need to add our own `required` attr here, as symfony does not always render the `required` form view variable see: https://github.com/symfony/symfony/blob/b1b77f366d42a58c1cd0879c605b997d05279d01/src/Symfony/Bridge/Twig/Resources/views/Form/form_div_layout.html.twig\#L59-L61
