chore: Enhance CMake and CI configurations for improved vcpkg integration

- Updated CMakeLists.txt to provide clearer logging and error messages for vcpkg integration, including detailed status reports for toolchain and triplet settings.
- Modified CI workflows to utilize manifest mode for vcpkg installations, improving dependency management and build reliability.
- Enhanced SDL2 and gRPC configurations to prioritize vcpkg packages, ensuring faster builds and clearer fallback mechanisms.
- Improved overall CMake structure for better readability and maintainability, including updated messages for build configurations and warnings.
