feat: prototype for using the databus with ACIR opcode

[guipublic]

Related to noir-lang/noir#4974

The PR implements logic in BB to handle ACIR opcodes for the databus.
Because the databus in BB works only with Goblin which is not yet supported by Noir, the code is not fully tested, so this is only prototype code.
Using the databus with UltraPlonk will result in a failing ASSERT.
I have updated the BB unit test to work with GoblinPlonk, so the BB code is tested.

Benchmark results

No base data found for comparison.

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.

[ledwards2225]

LGTM. I just left one comment around how block constraints are set. It seems to me that there's room for improvement there but this might not be the time/place. If you feel like adding some comments there though that would be helpful
