Allowing to consume the frozen_mutation directly to a stream rather than unfreezing it first and then consuming the unfrozen mutation. Streaming directly from the frozen_mutation saves both cpu and memory, and will make it easier to be made async as a follow, to allow yielding, e.g. between rows. This is used today only in to_data_query_result which is invoked on the read-repair path.
