Add nightly M1 Mac testing

[Reviewed by @daviditen]

Add comm=none release/example M1 testing. We want to increase the amount
of testing we do over time, but to start we just want to get some
testing going. Note that this adds a suppression for a known bug with
the fileIO primer on M1 (#19218)

Part of Cray/chapel-private#2625
