Default to fifo tasking layer on arm based macs [reviewed by @bradcray and @gbtitus] Qthreads doesn't currently support arm based macs. Configure fails with `error: What kind of a Mac is this?` while trying to figure out what native assembly to use for context switching. We started looking at using system `ucontext` in sandialabs/qthreads#90, but given how close our release is we want to default to fifo since we know some users have had success with that. Resolves Cray/chapel-private#2424 Part of #17911

@bradcray I think, but am not positive that the first two major bullets are done. Do you agree? |

As far as I know (based on the Homebrew CI checks), but I don't have an M1 Mac to download and test on to be sure. If you've verified them, it'd be fine with me to check those off. |

I'm going to go ahead and close this since we're in better shape with M1 Macs and the single remaining known issue is still open and can stand for itself. (i.e., this issue was designed to bring attention to a handful of problems and I think has served that purpose). |

This issue generally asks "How is Chapel doing on Macs with M1 chips?" where I think we mostly don't have much experience within the core team. It would be good to be able to have access to one in-house to take stock of things.
We have had a user mention on Gitter that they were able to download from GitHub and build from source. The GASNet's team seems to reflect this as well.
At present we know:
