feat!: add blake3 blackbox function to acir format

[TomAFrench]

Resolves noir-lang/noir#3171

We've started adding breaking changes to the serialisation so I thought I'd chuck this in.

Checklist:

Remove the checklist to signal you've completed it. Enable auto-merge if the PR is ready to merge.

• If the pull request requires a cryptography review (e.g. cryptographic algorithm implementations) I have added the 'crypto' tag.
• I have reviewed my diff in github, line by line and removed unexpected formatting changes, testing logs, or commented-out code.
• Every change is related to the PR description.
• I have linked this pull request to relevant issues (if any exist).

Can you point it to #3858 as reports gate diff is failing?

Benchmark results

Metrics with a significant change:

• note_successful_decrypting_time_in_ms (8): 507 (+32%)
• note_trial_decrypting_time_in_ms (8): 16.3 (-83%)

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.

Values are compared against data from master at commit 88fcf8d3 and shown if the difference exceeds 1%.
