HotSpot needs an update for Windows compiler versions:
recognises the Windows compiler VS2017 as _MSC_VER 1912.

VS 15.6.1 == 1913

My VS2017 Version 15.6.1 has:

** Visual Studio 2017 Developer Command Prompt v15.6.1

$ cl.exe
Microsoft (R) C/C++ Optimizing Compiler Version 19.13.26128 for x64

We need to update open/src/hotspot/share/runtime/vm_version.cpp to avoid seeing "unknown MS VC++" in the long VM version string.

In case I find reference to the link version in the src, thiis comes with link.exe:

Microsoft (R) Incremental Linker Version 14.13.26128.0

Fix Request Request to push to 11u to avoid a regression compared to 8u. Simple ifdef updates, low risk, no test coverage. Patch applies cleanly.
