patch 9.2.0474: MS-Windows: hard to tell which Visual Studio version was selected with MSVC

Problem:  When running msvc*.bat there is no indication of which
          Visual Studio version and target architecture got
          selected.
Solution: After vcvarsall.bat returns, echo the VS version, VC
          tools version and target architecture, and set the
          Command Prompt title accordingly (Ken Takata).
