Update rendering and resource management

Changed the `EditorState` class to use a timeout in the `WaitForGPUReady` method for improved responsiveness.
Changed the `nativeDebugging` setting in `launchSettings.json` to `false` for the "Ghost.Editor (Package)" profile.
Changed the `D3D12Renderer` class to set the swap chain only for the composition target type and replaced back buffer reset with dispose.
Changed the mapping of resources in `D3D12Resource` to use a pointer for improved safety and clarity.
Changed the `Mesh` class's upload buffer creation to not use the `true` flag for better memory management.
Added a new `Vertex` struct with a `StructLayout` attribute for improved interoperability with unmanaged code.
Refactored the `GraphicsPipeline` class to replace `IsGpuReady` with `WaitForGPUReady`, including a timeout parameter.
Added a constant buffer to the HLSL source code in `MeshRenderPass` for passing transformation matrices to the vertex shader.
Expanded the `UnitTestAppWindow` class to include event handlers for window activation and size changes for better resource management.
Updated the XAML for `UnitTestAppWindow` to include a `SwapChainPanel` and corrected the XML declaration for formatting consistency.
