feat!: remove key registry

[nventuro]

This removes the KeyRegistry contract and all mentions of it. All key rotation functions are removed from the wallets, tests, etc. The function to fetch public keys now simply queries the oracle and checks that the preimage is correct.

Benchmark results

Metrics with a significant change:

• app_circuit_witness_generation_time_in_ms (FPC:fee_entrypoint_public): 45.1 (+114%)
• app_circuit_witness_generation_time_in_ms (Benchmarking:create_note): 50.5 (-34%)
• avm_simulation_time_ms (Token:mint_public): 254 (+501%)
• avm_simulation_time_ms (Token:assert_minter_and_mint): 241 (-45%)

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.
