ot::Dns::Client::BrowseResponse::GetServiceInstance() const method

Gets a service instance associated with a DNS browse (service instance enumeration) response. MUST only be used from `BrowseCallback`. A response may include multiple service instance records. @p aIndex can be used to iterate through the list. Index zero gives the the first record. When we reach end of the list, `kErrorNotFound` is returned. Note that this method gets the service instance label and not the full service instance name which is of the form `..`.
