RFR : 8211106: [windows] Update OS detection code to recognize Windows Server 2019

[Bob Vandette]

Matthias,

We don’t usually add logic to the JDK related to unreleased operating system previews.

Has the ReleaseID been updated on the system you are testing on?

This is the documented way of determining the OS version you are running on?

The latest preview release is build 17744.  Are you testing on that release?
