test: refactor public cross chain tests for speed

[LHerskind]

Fixing #6055, time goes from 400 seconds -> 150 seconds.

Minor issues when dealing with the snapshots across instances as the cross chain harness is taking the pxe and node as args for its constructor so if going directly from snapshot could run into issue where it is connected to a different instance or the like.

Also ran into a deserialization issue for the aztec address, unclear why as it seems like it have been registered 🤷

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.

L2 block published to L1

Each column represents the number of txs on an L2 block published to L1.
