feat: enable UltraHonk verifier

[alexghr]

Fix #7373

[spalladino]

LGTM, but shouldn't we generate the contract as part of the compilation process, rather than on-the-fly? Or is it so fast that it doesn't make a difference?

[alexghr]

Ah you're right, we used to do this but I think it got removed from the Earthfile. I'll restore

[spalladino]

I'll restore

We can always restore in another PR once we see this works!

Detailed results

All benchmarks are run on txs on the Benchmarking contract on the repository. Each tx consists of a batch call to create_note and increment_balance, which guarantees that each tx has a private call, a nested private call, a public call, and a nested public call, as well as an emitted private note, an unencrypted log, and public storage read and write.

This benchmark source data is available in JSON format on S3 here.

The code to generate the contract was alreayd there, I just updated the name so that the deploy command finds the cached file :)
