VS: Handle build target correct for .NET SDK style projects with Any CPU

* Extend Visual Studio solution parser for reading build target
* Map solution build target to project build target (especially for Any CPU)
* Use C++ <optional> template instead of pointer return value for cmSlnData::GetProjectByGUID
