Refactor ECS framework and improve performance

Browse Source 
Refactored `ArcEntityTest` to use updated `Transform` and `Mesh` components, improving query logic with `GetChunkIterator` and introducing `ForEach` methods for better modularity.

Enhanced `Chunk` and `Archetype` structs with `readonly` properties and memory optimizations. Fixed bugs in memory copy logic and entity relocation.

Improved `EntityManager` with proper disposal handling, added a destructor, and fixed pointer usage in `AddComponent` and `SetComponentData`.

Refactored `EntityQuery` to use `ChunkIterator` and `ChunkView` for better abstraction. Simplified `EntityQueryMask` logic for performance.

Introduced templated `ForEach` methods and `ForEachWithEntity` methods, dynamically generated using T4 templates for scalability.

Added disposal logic for archetypes and queries in `World`. Updated `Program.cs` to include memory debugging setup.

Integrated T4 templates for dynamic code generation and added helper functions for template generation. Updated project file to include templates and generated outputs.

General improvements include enforcing immutability, optimizing memory management, and adding debugging/logging for better traceability.
