RFR [XS]: 8235243: handle VS2017 15.9 and VS2019 in abstract_vm_version

[Baesken, Matthias]

Hello, please review this small enhancement  for Visual Studio  compiler version handling.

The C++ compiler handling coding in abstract_vm_version.cpp currently misses handling nicely VS2017 15.9  ("update 9") and VS2019.
This leads to bad output like "unknown MS VC++:1916" in the hs_err file.

A list of  _MSC_VER  can be found for example here :
