Refactor and enhance resource management and rendering

Updated multiple components to improve encapsulation, maintainability, and performance. Key changes include:

- Upgraded package dependencies in project files.
- Refactored `Mesh` and `RenderingContext` to use properties and added support for per-object constant buffers.
- Improved resource management in `D3D12CommandBuffer`, `D3D12CommandQueue`, and `D3D12ResourceAllocator` with better encapsulation and disposal handling.
- Added validation for constant buffer sizes in `D3D12PipelineLibrary`.
- Simplified `MeshBuilder` methods to accept allocators and removed hardcoded values.
- Enhanced debugging with `GPUResourceLeakException` and resource tracking updates.
- Updated shaders and rendering logic for testing, including hardcoded triangle rendering.
- Removed redundant base classes and interfaces for cleaner code structure.
