Refactor vcpkg integration and enhance Windows build documentation

- Removed unnecessary dependencies from vcpkg.json for a cleaner configuration.
- Updated sdl2.cmake to improve handling of ZLIB and PNG dependencies for minimal builds on Windows.
- Added a comprehensive Visual Studio setup guide to assist users in configuring the YAZE project on Windows, including prerequisites and troubleshooting tips.
- Improved app configuration to prevent conflicts with Google Test integration, ensuring a smoother testing experience.
