mac-arm64: Don’t attempt to determine the CPU frequency

Apple has never exposed the CPU frequency on ARM systems. Report it as 0
on mac-arm64 without attempting to obtain it from the system (which
would log a warning in the process).

This will resolve these harmless warnings produced when Crashpad creates
a snapshot on arm64:

[pid:tid:yyyymmdd,hhmmss.µµµµµµ:WARNING system_snapshot_mac.cc:50] sysctlbyname hw.cpufrequency: No such file or directory (2)
[pid:tid:yyyymmdd,hhmmss.µµµµµµ:WARNING system_snapshot_mac.cc:50] sysctlbyname hw.cpufrequency_max: No such file or directory (2)
