Description of changes

Adds UTM: a GUI application for managing virtual machines on macOS.

---

I starting trying to build UTM from source but ended up just packaging their binary releases instead. I think it's not impossible to build UTM from source within the sandbox but I think it'll end up taking a fair amount of effort.

We would need to:

• essentially recreate most of build_dependencies.sh in the package
  • most of the deps are already in nixpkgs
  • we'd still want to use UTM's QEMU instead of the one in nixpkgs
  • we'd want separate derivations for the deps that we do build (at a glance this looks like: qemu, spice, angle, epoxy, virglrenderer plus some tools like depot/gclient) and then assertions in the main UTM derivation that check that the versions we built match what's supposed to be in the UTM release
• figure out what to do for entitlements
  • despite what the UTM docs say, I think it's possible to get by with ad-hoc signing; I think this is essentially the same issue as was already solved for QEMU in nixpkgs (qemu: enable hvf acceleration on aarch64-darwin #139960)
• get UTM to build with xcbuild instead of real xcodebuild
  • this is the real blocker; xcbuild doesn't seem to have real swift support and it falls over immediately on the subcommands used in UTM's build script

So for now I just have this package pull the DMG from the UTM GitHub releases. FWIW, this is what homebrew seems to do as well.

Worked for me just fine.
