feat: request specific transactions through the p2p layer

[Maddiaa0]

Overview

This pr creates a system for a node to request specific information from it's peers via the p2p request response layer.
We contain an interface for transactions, but it is trivial given the infrastructure to extend this to support requesting attestations or other information.

• This pr does NOT add this method as default whenever a transaction cannot be found in the tx pool.

tempted to move this integration test into the e2e, as it takes a bit of time to run (50 seconds)

Benchmark results

Metrics with a significant change:

• avm_simulation_time_ms (Token:mint_public): 44.5 (-36%)
• avm_simulation_time_ms (Token:assert_minter_and_mint): 67.0 (+66%)

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.
