Refactor component registration, update deps, improve JSON

- Updated Misaki.HighPerformance package versions in Core and Graphics projects.
- Added IsTrimmable to Ghost.Engine.csproj for trimming support.
- Renamed GetOrRegisterComponent to GetOrRegisterComponentID and updated all usages.
- Component registration codegen now uses a static class with [ModuleInitializer], no longer requires [EngineEntry].
- Improved JSON serialization: added string support, introduced Utf8JsonObjectScope/ArrayScope, and new extension methods for cleaner JSON writing.
- Removed [SkipLocalsInit] from Hierarchy and LocalToWorld.
- Fixed Entity.Invalid to use INVALID_ID for both fields.
- Minor cleanup: clarified comments, reorganized Ghost.Generator in solution, and disabled component serialization generator.
