[jdk15u-dev] RFR: 8274840: Update OS detection code to recognize Windows 11

[Olga Mikhaltsova]

I'd like to backport JDK-8274840 to jdk15u for parity with jdk11u.
The original patch applied cleanly.
Tested with a simple test printing OS version on Windows 11 and 10:

public class Main {
    public static void main(String[] args) {
        System.out.println(System.getProperty("os.name"));
    }
}
