Introduce a Roslyn analyzer to enforce unique ownership semantics for structs marked with the `[NonCopyable]` attribute. Added a corresponding code fix to resolve violations by suggesting the use of `Share()` or other ownership transfer methods.

Key changes:
- Added `StructCopyCodeAnalyzer` to detect invalid struct copies.
- Implemented `StructCopyCodeFixProvider` to provide code fixes.
- Created `Misaki.HighPerformance.Analyzer` and `CodeFixes` projects.
- Added unit tests for the analyzer and code fixes.
- Introduced `UniquePtr<T>` and `SharedPtr<T>` for pointer ownership.
- Added a Visual Studio extension project and packaging support.
- Updated `UnsafeUtility` to use `nint`/`nuint` for indices.
