chore: reintroduce /WHOLEARCHIVE linking for protobuf at executable level

- Added /WHOLEARCHIVE linking for protobuf in various CMake files to ensure internal symbols are included while preventing resource duplication.
- Updated linking options for `yaze`, `yaze_emu`, `z3ed`, and test suites to apply this option conditionally on Windows with MSVC.

Benefits:
- Ensures proper inclusion of protobuf symbols in executables, improving compatibility and functionality across platforms.
