Enabling is_error or error_text and other ControlState options for more controls, especially input controls

[Jon-Al]

I'm thinking about Checkbox's is_error and TextField and Dropdown's error_text. I think that enabling access to the ControlState of controls would be very useful, especially for SearchBar and AutofillGroup. It would enable creating a Dropdown with other filtering/searching algorithms (Regex, string-distance algorithms, etc), by using SearchBar with a set number of options, if it makes sense.
