Merge bitcoin/bitcoin#27918: fuzz: addrman, avoid `ConsumeDeserializable` when possible

025fda0a76893d09d19ec9a6c0ba86ad11c466f7 fuzz: addrman, avoid `ConsumeDeserializable` when possible (brunoerg)

Pull request description:

  Using specific functions like `ConsumeService`, `ConsumeAddress` and `ConsumeNetAddr` may be more effective than using `ConsumeDeserializable`. They always return some value while `ConsumeDeserializable` may return `std::nullopt`.

  E.g.: In this part of the code, if `op_net_addr` is `std::nullopt`,  we basically generated the addresses (if so) unnecessarily, because we won't be able to use them:
  ```cpp
  std::vector<CAddress> addresses;
  LIMITED_WHILE(fuzzed_data_provider.ConsumeBool(), 10000) {
      const std::optional<CAddress> opt_address = ConsumeDeserializable<CAddress>(fuzzed_data_provider);
      if (!opt_address) {
          break;
      }
      addresses.push_back(*opt_address);
  }
  const std::optional<CNetAddr> opt_net_addr = ConsumeDeserializable<CNetAddr>(fuzzed_data_provider);
  if (opt_net_addr) {
      addr_man.Add(addresses, *opt_net_addr, std::chrono::seconds{ConsumeTime(fuzzed_data_provider, 0, 100000000)});
  }
  ```

  Also, if we are not calling `Add` effectively, it would also be affect other functions that may "depend" on it.
