Iyyappa Murugandi c93e85d87e VS: Use Visual Studio Installer to locate VS 2017 
VS 2017 and later may no longer populate the Windows Registry entries
CMake has traditionally used to find the VS installations.  This is
because VS now supports having multiple installations of the same
version.  The Visual Studio Installer tool provides a COM interface we
can query to locate installations.
