feat: measuring node round trips

[benesjan]

Fixes https://linear.app/aztec-labs/issue/F-230/improve-benchmarks

In this PR I measure the number of node round trips. This is achieved by updating ProxiedNode to track this. This is done by having an inFlightCount counter tracking num current rpc calls. This allows us to group parallel rpc calls into the same round trip.

Note that the ProxiedNode is not used on next but when I activated it with the following change:

  #getSimulatorForTx(overrides?: { contracts?: ContractOverrides }) {
    const proxyContractDataProvider = ProxiedContractDataProviderFactory.create(
      this.contractDataProvider,
      overrides?.contracts,
    );

    return new ContractFunctionSimulator(
      proxyContractDataProvider,
      this.noteDataProvider,
      this.keyStore,
      this.addressDataProvider,
-      this.node,
+      ProxiedNodeFactory.create(this.node),
      this.anchorBlockDataProvider,
      this.senderTaggingDataProvider,
      this.recipientTaggingDataProvider,
      this.senderAddressBook,
      this.capsuleDataProvider,
      this.privateEventDataProvider,
      this.simulator,
    );
  }

I got what looks like reasonable values when running src/bench/client_flows/amm.test.ts:

    {
        "name": "ecdsar1+amm_add_liquidity_1_recursions+private_fpc/round_trips",
        "value": 89,
        "unit": "round_trips"
    },
    {
        "name": "ecdsar1+amm_add_liquidity_1_recursions+private_fpc/round_trips_blocking_time",
        "value": 166.96370199995,
        "unit": "ms"
    }

The linked issue F-230 seems to have a wider scope than just the round trip measurements so not sure if we want to fully close it with this PR.
