feat: flamegraph helper script

[benesjan]

I found it quite tedious to actually get a flamegraph so I've created this utility script which builds the profiler (if not available) sets all the params for noir contracts, gets the function artifact and serves the file over http.

Benchmark results

Metrics with a significant change:

• proof_construction_time_sha256_30_ms (16): 1,660 (+19%)
• avm_simulation_time_ms (Token:mint_public): 435 (-27%)
• avm_simulation_time_ms (Token:assert_minter_and_mint): 217 (+189%)
• protocol_circuit_witness_generation_time_in_ms (private-kernel-inner): 1,087 (+16%)

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.
