mac arm64: Provide something more useful from SystemSnapshot::CPURevison

hw.cputype is just CPU_TYPE_ARM64, which isn’t terribly useful.
hw.cpufamily is somewhat better as it uses <mach/machine.h> CPUFAMILY_*
values, which distinguish between different CPU generations.
CPUFAMILY_ARM_VORTEX_TEMPEST identifies A12, for example. (The fun cores
are Vortex and the boring cores are Tempest.)
