Add Ghost.Nvtt C# wrapper and integrate nvtt texture pipeline

- Introduce full managed C# wrapper for NVIDIA Texture Tools (nvtt) with safe handle classes, idiomatic APIs, and managed callback support.
- Integrate Ghost.Nvtt into Ghost.Editor.Core and Ghost.MicroTest; update TextureAssetHandler to use the new nvtt wrapper for texture compression.
- Add comprehensive end-to-end binding test (NvttBindingTest).
- Refactor D3D12 resource management: add deferred/immediate release APIs, update allocator/database usage, and ensure proper resource cleanup.
- Update project files for new native DLL layout and dependency versions.
- Minor API cleanups: EditorApplication properties, D3D12 input layout, and removal of obsolete code.
- Update shaders, tests, and documentation for new APIs and usage patterns.
