Refactor namespaces and improve resource handling

- Updated namespaces from `Ghost.UnitTest` to `Ghost.Graphics.Test` across multiple files.
- Refactored `GraphicsTestWindow` to use a new `RenderSystem` configuration.
- Removed deprecated `Logger` and `SerializationTest` classes.
- Improved memory management in D3D12 components, including resource allocation and cleanup.
- Added `[SupportedOSPlatform]` attributes to specify Windows version compatibility.
- Updated `.editorconfig` settings and project references for consistency.
- Enabled `nativeDebugging` in `launchSettings.json`.
