A significant chunk of the time on the macos CI task is spent installing packages using homebrew. The downloads of the packages are cached, but the installation needs to happen every time. We can't cache the whole homebrew installation, because it is too large due to pre-installed packages. Speed this up by installing packages using macports and caching the installation as .dmg. That's a lot faster than unpacking a tarball. In addition, don't install llvm - it wasn't enabled when building, so it's just a waste of time/space. This substantially speeds up the mac CI time, both in the cold cache and in the warm cache case (the latter from ~1m20s to ~5s). It doesn't seem great to have diverging sources of packages for CI between branches, so backpatch to 15 (where CI was added).
