Obsolete the VM option UseUTCFileTimestamp

Summary

Obsolete the VM option UseUTCFileTimestamp.

Problem

The UseUTCFileTimestamp is a VM option for the windows platform. It was introduced for fixing JDK-6539723. After the fix for JDK-8188122, the option is no longer used. Therefore, the UseUTCFileTimestamp VM option should be made obsolete.

Solution

This is a windows-only vm option. So the option needs to be removed from the global_windows.hpp. The option also needs to be added to the obsolete section of the special_vm_flags table in arguments.cpp.
