CI: Switch macos aarch64 to nightly

ehuss · ehuss · commit afe0b2de7aa9 · 2024-08-09T18:08:28.000-07:00
We will be promoting aarch64-apple-darwin to tier 1 soon via rust-lang/rust#128592. This updates our CI so that aarch64-apple-darwin runs the full test suite on nightly to keep this in-line with tier-1 support. This also removes the x86_64 stable macos job and replaces it with aarch64, mainly because aarch64 runs much faster, and presumably x86_64 support will go away some day.
