feat(build): align Windows static builds with vcpkg runtime settings

- Updated CMake configuration to align Windows static builds (MSVC, clang-cl) with vcpkg's /MT runtime.
- Added conditional linking for libprotobuf when YAZE_WITH_GRPC is enabled, enhancing modularity.
- Addressed potential macro conflicts by undefining SendMessage in the conversational agent service files.

Benefits:
- Improves compatibility and reliability of builds on Windows platforms.
- Enhances the flexibility of the build system by conditionally linking libraries based on configuration options.
