Enable feature detection on all Apple/Darwin targets

Tested in the simulator and on the device I had lying around, a 1st
generation iPad Mini (which isn't Aarch64, but shows that the
`sysctlbyname` calls still work even there, even if they return false).

`sysctlbyname` _should_ be safe to use without causing rejections from
the app store, as its usage is documented in:
https://developer.apple.com/documentation/kernel/1387446-sysctlbyname/determining_instruction_set_characteristics

Also, the standard library will use these soon anyhow, so this shouldn't
affect the situation:
