refactor(build): enhance CMake configurations for protobuf integration

- Updated CMake files to conditionally link against libprotobuf based on the YAZE_PROTOBUF_TARGET variable across various modules (core, net, agent, z3ed).
- Ensured consistent use of the static MSVC runtime to align with vcpkg static triplets.
- Improved clarity in build logs by adding status messages for whole-archive linking conditions.

Benefits:
- Enhances modularity and compatibility of the build system with protobuf.
- Streamlines the build process for different platforms by ensuring appropriate linking based on configuration options.
