Confirm Semi-coupled form elements can work with autocomplete

Added a test module in the MR and found that the autocomplete inputs (which had been proven to work in the past but never got test coverage) no longer work due to the input now using the Radix TextField component. This component intercepts a few props, including className and applies them to the input's parent <div> instead of the <input/> and Drupal's autocomplete initializes based on the presence of .form-autocomplete on an <input/> element.

Between this issue and 📌 Confirm Semi-coupled form elements can work with State API visibility Active , if we want to continue using Radix we need to have a way to customize the attributes sent to the input elements within the component. I filed an issue with primitives about doing this with Checkbox, and if that is welcomed I'll do the same in Radix themes for the TextField component
