Add tentative entry for Apple M1 #24

refers to https://github.com/archspec/archspec/issues/38

This PR adds an entry for Apple M1. Currently I don't have a CPU to test on, so I'm coding this based on reported output from sysctl. It seems we don't have much information from Apple, in particular concerning CPU features. I think that all the features listed as hw.optional should be added to the JSON file but I still need to double check if this is consistent with the semantics of other aarch64 architectures.

Also, the compiler flags are generic for armv8.4-a and not tested on any actual application. It would be good if reviewers could comment on that.

@gonsie I think with the changes here you'll be able to detect Apple M1. There's work I still need to do though to check which are the correct features to be stored in the JSON file and to add proper compiler support for at least gcc, clang (LLVM) and apple-clang.

I think we can merge this as is, and improve later on compiler flags.
