lib/logstorage: improve performance for stream_context pipe over streams with big number of log entries
Do not read timestamps for blocks, which cannot contain surrounding logs.
This should improve peformance for https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6730 .

Also optimize min(_time) and max(_time) calculations a bit by avoiding conversion
of timestamp to string when it isn't needed.
This should improve performance for https://github.com/VictoriaMetrics/VictoriaMetrics/issues/7070 .
