CMakeDetermineCompilerABI: Link with standard libraries on MSVC

Browse Source 
In commit v2.8.0~395 (Implicit link info for C, CXX, and Fortran,
2009-07-23) we added a '-DCMAKE_${lang}_STANDARD_LIBRARIES=' flag to the
try_compile used to build the ABI detection project.  It is needed when
detecting the implicit libraries added by the GNU compiler on Windows
(MinGW tools) to avoid contaminating the list with standard Windows
libraries.  However, with MSVC we do not detect such implicit link
libraries anyway, and for some target platforms (e.g. Windows Phone) we
may need the standard libraries to link the ABI detection executable.
Drop the flag when detecting the ABI using MSVC.
