fix: serialize AvmVerificationKeyData

[alexghr]

This PR adds a integration test for the RPC layer between the queue and agent to validate that all the function calls correctly encode/decode their inputs and outputs.

Benchmark results

Metrics with a significant change:

• l2_block_processing_time_in_ms (4): 257 (-27%)
• l2_block_processing_time_in_ms (16): 821 (-29%)

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.
