CI: rework to account for new cmake behavior

* CMakeLists: pass `-Dstrip` for release zig builds
 * pass -target and -mcpu to zig1. works around llvm on freebsd
   incorrectly detecting "freestanding" instead of "freebsd" for the
   native OS.
 * ci.ziglang.org is now responsible for creating aarch64-macos tarballs
   rather than Azure.
