According to GitHub documentation it is now possible to get a Mac M1 runner using the aarch64 architecture. This means x86_64 is no longer the only host architecture for which we expect the x86_64-apple-darwin target to always be natively installed.
Install it unconditionally next to the aarch64 Mac/iOS triples and let rustup figure out and skip what's already installed.
