RFR: 8370393: Cleanup handling of ancient Windows versions from GetJavaProperties java_props_md

[Matthias Baesken]

There are some ancient Windows versions still handled in GetJavaProperties :

https://github.com/openjdk/jdk/blob/master/src/java.base/windows/native/libjava/java_props_md.c#L456

We compile currently with Windows 8+ settings :


# _WIN32_WINNT=0x0602 means access APIs for Windows 8 and above. See
# https://docs.microsoft.com/en-us/cpp/porting/modifying-winver-and-win32-winnt?view=msvc-170
ALWAYS_DEFINES="-DWIN32_LEAN_AND_MEAN -D_WIN32_WINNT=0x0602 \


So everything older than Windows 8 could most likely be removed.
