Minor - Implements component serialization - V12.9.0

Adds serialization and deserialization functionality to the ECS component system.

This allows components to be saved and loaded, enabling scene persistence.
The IdentityComponent is updated to support serialization/deserialization.
The scene saving logic in scene_manager is updated to serialize components instead of hardcoded values.
