Refactor and enhance rendering pipeline

- Added new C# formatting rules in .editorconfig.
- Introduced `IKeyType`, `Key<T>`, and `Ptr<T>` structs.
- Updated `Result` and `Result<T>` for implicit conversions.
- Added AOT compatibility to project files.
- Introduced a `Camera` class and refactored namespaces.
- Enhanced rendering with bindless support and pipeline state management.
- Refactored `D3D12CommandBuffer` for new rendering features.
- Improved `D3D12PipelineLibrary` with disk caching methods.
- Added support for UAVs and raw buffers in `D3D12ResourceAllocator`.
- Improved shader compilation and reflection in `D3D12ShaderCompiler`.
- Refactored descriptor heap and swap chain initialization.
- Added enums and structs for rendering configurations.
- Expanded `ICommandBuffer` and `IPipelineLibrary` interfaces.
- Updated `MeshRenderPass` to align with the new pipeline.
- Consolidated namespaces and improved code maintainability.
