8368087: ZGC: Make ZStatLoad::print() logging conditional on os::loadavg support

[xmas92]

ZStatLoad::print() logs the load average on the machine, however it does not check whether the operation is supported or not. This results in printing a load average of 0/0/0 on Windows which is a bit misleading.
