feat: Enhance gRPC configuration and add dungeon test harness

- Updated gRPC configuration to use version 1.67.1, improving compatibility with modern compilers and fixing MSVC template issues.
- Enhanced warning messages for missing vcpkg gRPC installation, providing clearer instructions for faster builds.
- Introduced a new dungeon test harness tool to capture and dump the state of WRAM and CPU/PPU registers, aiding in emulator testing and development.
- Organized source groups in CMake for better structure and clarity in the input and UI systems.

 # Windows-optimized gRPC configuration using vcpkg
 # This file provides fast gRPC builds on Windows using pre-compiled packages
+#
+# Benefits:
+# - vcpkg build: ~5 minutes (pre-compiled)
+# - FetchContent build: ~45 minutes (compile from source)
+#
+# To use vcpkg (recommended):
+#   vcpkg install grpc:x64-windows
+#   cmake -DCMAKE_TOOLCHAIN_FILE=<vcpkg-root>/scripts/buildsystems/vcpkg.cmake ..
