lib/logstorage: avoid reading columnsHeader data when field_values pipe is applied directly to log filters
This improves performance of `field_values` pipe when it is applied to large number of data blocks.
This also improves performance of /select/logsql/field_values HTTP API.

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

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 .
