Refactor entity-component system and related classes

Changed the `Component` class to an interface `IComponentData` to support a data-oriented design.
Changed the `Transform` class from a class to a struct, implementing `IComponentData` and updating properties.
Changed the `GameObject` class to use a dictionary for components and added properties for state management.
Changed the `PlayerLoopService` class to `GameLoopService` and updated methods to integrate with the new `SceneManager`.
Changed the `World` class to manage multiple worlds and enhance entity management with new querying methods.

Added the `Scene` class to manage root game objects and their lifecycle.
Added new utility classes like `ComponentMask`, `Box<T>`, and `TypeHandle<T>` for better component management.
Added the `ScriptComponent` class to allow for modular scriptable components attached to entities.
Added the `QueryEnumerable` class to facilitate flexible querying of entities with specific components.

Updated the `Test` class in `Program.cs` to demonstrate the new entity and component management system.
Updated project files to include new references and settings supporting the changes made in the codebase.
