trace_processor: implement an iterator API and make trace to text use it This CL implements an iterator API which allows users of trace processor to pull values from queries rather than all values to be copied to protos This especially has a big impact on trace to text as we know that every line it queries from the trace processor will be a long string and moving to this model saves 3/4 of the run time on long traces.
