app/vlselect/logsql: clone the query with the current timestamp when performing live tailing requests in the loop
Previously the original timestamp was used in the copied query, so _time:duration filters
were applied to the original time range: (timestamp-duration ... timestamp]. This resulted
in stopped live tailing, since new logs have timestamps bigger than the original time range.

lib/logstorage: add blocks_count pipe
This pipe is useful for debugging purposes when the number of processed blocks must be calculated for the given query:

    <query> | blocks_count

This helps detecting the root cause of query performance slowdown in cases like https://github.com/VictoriaMetrics/VictoriaMetrics/issues/7070

app/vlselect: consistently reuse the original query timestamp when executing /select/logsql/query with positive limit=N query arg
Previously the query could return incorrect results, since the query timestamp was updated with every Query.Clone() call
during iterative search for the time range with up to limit=N rows.

While at it, optimize queries, which find low number of matching logs, while spend a lot of CPU time for searching
across big number of logs. The optimization reduces the upper bound of the time range to search if the current time range
contains zero matching rows.

lib/logstorage: it is safe using | unroll pipe in live tailing
`| unroll` pipe can make multiple copies of rows from the input row.
This doesn't break live tailing, so allow `| unroll` pipe in live tailing.

lib/logstorage: add abilty to speficy offset for the selected _time filter
The following syntax is supported: _time:filter offset off
For example:

- _time:5m offset 1h - 5-minute duration one hour before the current time
- _time:2023 offset 2w - 2023 year with the 2 weeks offset in the past
