ski 742cc8b01d 0027350: Support for Universal Windows Platform 
- Toolchain file to configure a Visual Studio generator for a Windows 10 Universal Application was added (CMake).
- There is no support for environment variables in UWP.
- SID is not supported (were excluded).
- Windows registry is not supported (were excluded).
- Mess with usage of Unicode/ANSI was corrected.
- Added sample to check UWP functionality.
- Excluded usage of methods with Unicode characters where it is possible.
- Minor corrections to allow building OCAF (except TKVCAF) and DE (except VRML and XDE)
- Building of unsupported modules for UWP platform is off by default .
- Checking of DataExchange functionality was added to XAML (UWP) sample.
- Added information about UWP to the documentation.
- Update of results of merge with issue 27801
