Core backed enum support

Yes, it seems like fixing ✨ Add support for PHP 8.1 Enums as allowed values for list_* data types Needs work would remove the need for this module. ✨ Add support for PHP 8.1 Backed Enums in Select, Checkboxes, Radio elements Needs work is unrelated, this module doesn't change anything about form elements. I'll update the project description.

Done! Thanks for letting me know.
