Support markerless serialization for bool and enum types

Extend markerless serialization to Boolean and Enum types in AcBinarySourceGenerator and generated writers. Updated IsMarkerlessType and EmitMarkerlessWrite to handle these types directly. Refactored generated code to write DateTime, int, enum, and decimal properties without type markers or property skip checks. Simplified OnStringInterned debug callback in AcBinarySerializer. These changes reduce serialization overhead and improve performance for supported types.
