Port remaining HECO evaluation artifacts and ensure they produce equivalently optimal results.

[j2kun]

@AlexanderViand-Intel I may need your help here. I haven't figured out how to build HECO yet (everything succeeds in your repo instructions up to the linking step, then it fails with a bazillion linker errors to LLVM).

What I think I'd want is just the output MLIR from each of the evaluation artifacts, so that I can compare the rotation counts in them with what HEIR produces. I tried manually porting roberts-cross, and I think I see where HEIR is still lacking, but I want some confirmation.
