Add new interfaces and refactor rendering logic

Added a new `ConstPtr<T>` struct for type-safe pointers.
Added a new `ICommandBuffer` interface for resource copying.
Added a new `IRenderPass` interface to define render passes.
Added a new `IResource` interface for GPU resources.
Added a new `IResourceAllocator` interface for resource management.
Added a new `ISwapChainPanelNative` struct for native interactions.
Added a new `D3D12Utility` class for Direct3D 12 utilities.
Added a new package reference for `Vortice.Win32.Graphics.D3D12MemoryAllocator`.

Changed project file to allow unsafe code blocks.
Changed `Result` struct methods to improve clarity.
Changed error handling in `ProjectService` and `AssetDatabase` to use `Result.Failure()`.
Changed `launchSettings.json` to enable native debugging.
Changed rendering logic in `ScenePage.xaml.cs` to use `IRenderer`.
Changed `IGraphicsDevice` interface to include renderer properties.
Changed `IRenderView` to `IRenderer` and updated its methods.
Changed `Mesh` class to use the new `IResource` interface for buffers.
Changed `GraphicsAPI` enum to include a `None` value.
Changed various aspects of the `GraphicsPipeline` class for new architecture.

Removed the old `DX12RenderView` class and replaced it with `DX12Renderer`.
Removed unnecessary code in the `ResourceView` class.
