> Enhance os::pd_print_cpu_info on macOS and Windows by information about CPU frequency and caches.
> On Windows , this info can be obtained by the Processor Power Information API or "powerbase" (CallNtPowerInformation , see https://learn.microsoft.com/en-us/windows/win32/api/powerbase/nf-powerbase-callntpowerinformation ); this is available since Windows Server 2003/XP.
> On macOS, sysctlbyname can be used.
