linkWindowsCppImplStubs function

void linkWindowsCppImplStubs(List<ModuleInfo> moduleInfos, { String baseDir = '.', })

Creates Windows-specific C++ impl stub files for modules that target windows: WindowsNativeImpl.cpp. These stubs live in windows/src/ so windows/CMakeLists.txt can reference them via a relative path.
