Hi all,

Please review this change:

   JBS: https://bugs.openjdk.java.net/browse/JDK-8233707
   webrev: http://cr.openjdk.java.net/~ysuenaga/JDK-8233707/webrev.00/

I tried to build OpenJDK with VS 2019 (16.3.8), but it couldn't as below.
(My laptop sets locale to Japanese, sorry)

c:/OpenJDK/jdk/src/java.desktop/windows/native/common/awt/systemscale/systemScale.cpp(96): error C2220: 次の警告はエラーとして処理されます
c:/OpenJDK/jdk/src/java.desktop/windows/native/common/awt/systemscale/systemScale.cpp(96): warning C4996: 'ID2D1Factory::GetDesktopDpi': Deprecated. Use DisplayInformation::LogicalDpi for Windows Store Apps or GetDpiForWindow for desktop apps.
c:\progra~2\wi3cf2~1\10\include\100183~1.0\um\d2d1.h(3355): note: 'ID2D1Factory::GetDesktopDpi' の宣言を確認してください

I could not find out the description for this deprecation in MSDN.
However, in case of Windows Terminal, this warning avoids with #pragma. So I think we can fix it in same way.
