os_windows.cpp : simplify is_thread_cpu_time_supported ?

[Baesken, Matthias]

Hello,  I wonder , should we just return  true  in  os::is_thread_cpu_time_supported()   on Windows  ?

See

https://github.com/openjdk/jdk/blob/master/src/hotspot/os/windows/os_windows.cpp#L4588


According to  MSDN
https://docs.microsoft.com/en-us/windows/win32/api/processthreadsapi/nf-processthreadsapi-getthreadtimes


GetThreadTimes is supported  on Win2003/XP and higher . This should be fine for OpenJDK .

Best regards, Matthias
