looks like the backport of "8233787: Break cycle in vm_version* includes" removed the handling of some VS versions (like _MSC_VER == 1923) from abstract_vm_version.cpp; this should be repaired.

This is the backport commit introducing the issue: https://github.com/openjdk/jdk11u-dev/commit/95c7d073e24227962e04f859d9c8bb06ceab861d

Those entries went missing:
