Update visual fire handling with TriState support (#12303)

Replaced the Boolean-based visual fire system with TriState for improved clarity and flexibility, enabling three distinct states: TRUE, FALSE, and NOT_SET. Deprecated older methods in favor of new ones and updated internal handling to reflect these changes. Adjusted serialization and deserialization logic to accommodate the new TriState implementation.
