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 .

lib/logstorage: read timestamps column when it is really needed during query execution
Previously timestamps column was read unconditionally on every query.
This could significantly slow down queries, which do not need reading this column
like in https://github.com/VictoriaMetrics/VictoriaMetrics/issues/7070 .
