VS 2017 and above come with a Visual Studio Installer tool that tracks four-component Visual Studio version numbers. We already detect the VS version number because it is needed to make some generation decisions. Provide the number to projects in a `CMAKE_VS_VERSION_BUILD_NUMBER` variable so they can use it similarly. Fixes: #24230
