Refactored `D3D12ResourceAllocator` to improve maintainability, introducing new descriptor creation methods, utility functions, and enhanced resource handling. Added thread safety and proper disposal logic. Updated `.editorconfig` to enforce consistent `using` directive sorting and increased max line length. Revised `BufferUsage` enum in `Common.cs` to include new flags and reorganized existing ones. Refactored `RenderTargetDesc` conversion to an instance method. Adjusted `MeshRenderPass` for consistency and added a parameter to `Execute`. Minor formatting updates in `ShaderCode.hlsl` and cleanup of unused directives in `D3D12Utility.cs`. Overall, these changes enhance readability, maintainability, and functionality.
