RFR: 8351359: OperatingSystemMXBean: values from getCpuLoad and getProcessCpuLoad are stale after 24.8 days (Windows)

[Kevin Walls]

OperatingSystemImpl.c on Windows is limited by its use of clock(), which hits its limit with longer process uptimes.

https://learn.microsoft.com/en-us/cpp/c-runtime-library/reference/clock?view=msvc-170
"maximum clock function return value of 2147483.647 seconds, or about 24.8 days"

The linked alternative, time(), gives 64-bit time but only seconds.  In the example code for time(), there is use of _ftime() to retrieve milliseconds.

The example code also notes that _ftime is deprecated, so _ftime_s is used here.
