lib/logstorage: pre-calculate hashes from tokens used in bloom filter search

Browse source 
Previously per-token hashes for per-block bloom filters were re-calculated on every scanned block.
This could be slow when the number of tokens is big or when the number of blocks to scan is big.
Pre-calculate hashes for bloom filters and then use them for searching in bloom filters.
This improves performance by 2.5x for in(...) filters with many values to search inside `in()`.

@ -15,6 +15,7 @@ according to [these docs](https://docs.victoriametrics.com/victorialogs/quicksta
## tip
* FEATURE: optimize [multi-exact queries](https://docs.victoriametrics.com/victorialogs/logsql/#multi-exact-filter) with many phrases to search. For example, `ip:in(path:="/foo/bar" | keep ip)` when there are many unique values for `ip` field among log entries with `/foo/bar` path.
* FEATURE: [web UI](https://docs.victoriametrics.com/victorialogs/querying/#web-ui): add support for displaying the top 5 log streams in the hits graph. The remaining log streams are grouped into an "other" label. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6545).
* FEATURE: [web UI](https://docs.victoriametrics.com/victorialogs/querying/#web-ui): add the ability to customize the graph display with options for bar, line, stepped line, and points.
* FEATURE: [web UI](https://docs.victoriametrics.com/victorialogs/querying/#web-ui): add fields for setting AccountID and ProjectID. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6631).
