IPO: INTERPROCEDURAL_OPTIMIZATION (LTCG) for Visual Studio
Add IPO support for Visual Studio (which is referred to by VS as
"Link Time Code Generation" and "Whole Program Optimization"), for
VS version >= 10. This allows CMake/VS users to enable IPO by setting
property `INTERPROCEDURAL_OPTIMIZATION`.
Fixes: #16748
