field-components: warn about fields that are both required and disabled

* previously, an error was raised in this case
* this broke edit forms where fields were marked as "create only" (and
  thus disabled on edit)
* according to the HTML spec, disabled fields are skipped during
  validation: https://html.spec.whatwg.org/multipage/form-control-infrastructure.html#enabling-and-disabling-form-controls%3A-the-disabled-attribute
