feat: Optimize constant array handling in brillig_gen

[sirasistant]

Optimize array initialization to avoid repeatedly computing pointers. Instead of tracking indices and recomputing pointers at every step, track the pointers and increase them at every step.

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.
