RFR: 8295017: Remove Windows specific workaround in JLI_Snprintf

Sun Oct 9 08:14:46 UTC 2022

The C99 snprintf is available with Visual Studio 2015 and above, alongside Windows 10 and the UCRT, and is no longer identical to the outdated Windows _snprintf. Since support for the Visual C++ 2017 compiler was removed a while ago, we can now safely remove the compatibility workaround on Windows and have JLI_Snprintf simply delegate to snprintf.
