feat: parity circuits

[benesjan]

Fixes #4633

Note: The new model currently can't be used to consume the message on L2 because old model root is being inserted to the messages tree in root rollup circuit. We can be sure the root computed by new model is correct because it is already being set in the header and checked in the Rollup contract. I will start inserting the new root in my next PR in which I'll purge the old inbox.

Benchmark results

Metrics with a significant change:

• l2_block_rollup_simulation_time_in_ms (8): 8,269 (+17%)
• note_successful_decrypting_time_in_ms (8): 131 (-47%)

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 6c706244 and shown if the difference exceeds 1%.

Originally had it as buffer because I didn't realize that we are already truncating the content hash to 1 field (I assumed we represent it as 2 fields as well).

[iAmMichaelConnor]

If possible, please could you add this Parity Circuit to the "Circuit Stats" that get created with each PR? It will be interesting to know and track the number of constraints of this circuit.

[iAmMichaelConnor]

Hmm... actually, I can't see the gate counts table. @sirasistant didn't we used to have a table of protocol circuit gate counts, which got created with each PR?

[sirasistant]

@iAmMichaelConnor It's here but broken #5082 (comment)
