Since JDK-8293117 was pushed to 17 SAP's windows build which uses VS2017 fails with a warning in test_atomic.cpp. The windwos build of the GHA actions which uses VS2019 works.

I don't want to do adaptions for an old compiler in the code, so I disable the warning for VS2017 only. There is already a section for VS2017 specific compiler settings in the build.

This change applies to 17u and older only as jdk20 and later don't support VS2017 any more, see JDK-8293162.
