lib/logstorage: read timestamps column when it is really needed during query execution

Browse source 
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 .

## tip
* FEATURE: [web UI](https://docs.victoriametrics.com/victorialogs/querying/#web-ui): add button for enabling auto refresh, similarly to VictoriaMetrics vmui. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/7017).
* FEATURE: improve performance of analytical queries, which do not need reading the `_time` field. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/7070).
* BUGFIX: properly return logs without [`_msg`](https://docs.victoriametrics.com/victorialogs/keyconcepts/#message-field) field when `*` query is passed to [`/select/logsql/query` endpoint](https://docs.victoriametrics.com/victorialogs/querying/#querying-logs) together with positive `limit` arg. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6785). Thanks to @jiekun for itentifying the root cause of the issue.
