feat(bindings): update C# wrappers for meshopt, nvtt, ufbx

Refactor and regenerate native C# bindings for Ghost.MeshOptimizer, Ghost.Nvtt, and Ghost.Ufbx to match updated native APIs and improve usability.
- Replace meshoptimizer.dll with newer version.
- Move meshoptimizer functions to static methods in partial class; add new meshlet, simplification, quantization features.
- Remove enum wrappers in favor of constants; delete meshopt_Allocator.cs.
- Regenerate native wrappers with PascalCase naming, XML doc comments, and aggressive inlining.
- Implement IDisposable for resource structs; update configs for naming, documentation, and method mapping.
- Update user code to use new wrapper classes and method names.
- Improve documentation and comments for clarity.

BREAKING CHANGE: API surface changes, wrapper class and method names updated, enum wrappers removed, custom allocator deleted.
