cpu: better defaults on darwin ARM64

Browse Source 
This is motivated by
https://github.com/wazero/wazero/pull/2473
which needs to special case darwin for testing the availability of
HasATOMICS, although all M-series CPUs support it.

We could do sysctlbyname, like syscall_darwin_x86_gc.go, if that's
preferred:
