fix(form): support inline fields group label for required attribute

A required Inline fields label does not get an asterisk and does not get a state color

To fix the state color i had to make use of the :has() class selector. This isnt supported by all browsers, so in those browsers this feature wont work.

I also fixed positioning of fields when an empty label is used
