Customizable autocomplete attribute for text fields to improve accessibility

[Supportic]

Currently it's only possible to toggle autocomplete on/off.
Setting it to off has even an invalid value in the frontend: autcomplete="off_82vmeLIU"

Since it's important for screenreaders and the browser builtin autocomplete functionality, I would recommend to implement the following features:

1. adding a suffix to the "off" value becomes an invalid value -> fix off value
2. implement mulitple text field components (regular text field, country text field, street text field) which inherently have already the correct autocomplete values
3. use a single text field component where the user has the possibility to override this autocomplete value for complex use cases
   3.1 display a select field with predefined given autocomplete values
   3.2 display a text field where the user can use a custom autcomplete value

Reason:

1. proper screenreader and browser detection of input fields
2. WCAG2.2 accessibility rule: https://www.w3.org/TR/WCAG22/#identify-input-purpose
