lib/logstorage: clear hits slice obtained from encoding.GetUint64s() before updating it with hits for valueTypeDict column
encoding.GetUint64s() returns uninitialized slice, which may contain arbitrary values.
So values in this slice must be reset to zero before using it for counting hits in `uniq` and `top` pipes.

lib/logstorage: add non-empty if (...) condition to automatically generated result names in stats pipe
This allows executing queries with `stats` pipe, which calculate multiple results with the same functions,
but with different `if (...)` conditions. For example:

  _time:5m | count(), count() if (error)

Previously such queries couldn't be executed becasue automatically generated name for the second result
didn't include `if (error)`, so names for both results were identical - `count(*)`.

Now the following queries are equivalents:

This is needed for convenience, since `order by` is commonly used in other query languages such as SQL.

lib/logstorage: properly return surrounding logs outside the selected time range by stream_context pipe
Previously only logs inside the selected time range could be returned by stream_context pipe.
For example, the following query could return up to 10 surrounding logs only for the last 5 minutes,
while most users expect this query should return up to 10 surrounding logs without restrictions on the time range.

    _time:5m panic | stream_context before 10

This enables the ability to implement stream context feature at VictoriaLogs web UI: https://github.com/VictoriaMetrics/VictoriaMetrics/issues/7063 .

Reduce memory usage when returning stream context over big log streams with millions of entries.
The new logic scans over all the log messages for the selected log stream, while keeping in memory only
the given number of surrounding logs. Previously all the logs for the given log stream on the selected time range
were loaded in memory before selecting the needed surrounding logs.
This should help https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6730 .

Reduce the scan performance for big log streams by fetching only the requested fields. For example, the following
query should be executed much faster than before if logs contain many fields other than _stream, _msg and _time:

    panic | stream_context after 30 | fields _stream, _msg, _time

app/vlinsert: support _time field without timezone information during data ingestion
Use local timezone of the host server in this case. The timezone can be overridden
with TZ environment variable if needed.

While at it, allow using whitespace instead of T as a delimiter between data and time
in the ingested _time field. For example, '2024-09-20 10:20:30' is now accepted
during data ingestion. This is valid ISO8601 format, which is used by some log shippers,
so it should be supported. This format is also known as SQL datetime format.

Also assume local time zone when time without timezone information is passed to querying APIs.
Previously such a time was parsed in UTC timezone. Add `Z` to the end of the time string
if the old behaviour is preferred.

feature: [victorialogs] drop logs without non-empty _msg field ()
### Describe Your Changes

VictoriaLogs allows logs without `_msg` field or `_msg` field is empty.
This lead to incorrect search result. See:
https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6785

This pull request search for non-empty `_msg` field before log entry is
added to `LogRows`.

New counter `vl_rows_dropped_total{reason="msg_not_exist"}` is
introduced.

Example log output:
```
2024-09-23T02:33:19.719Z        warn    app/vlinsert/insertutils/common_params.go:189   dropping log line without _msg field; [{@timestamp 2024-09-18T13:42:16.600000000Z} {Attributes.array.attribute ["many","values"]} {Attributes.boolean.attribute true} {Attributes.double.attribute 637.704} {Attributes.int.attribute 10} {Attributes.map.attribute.some.map.key some value} {Attributes.string.attribute some string} {Body Example ddddddddddlog record} {Resource.service.name my.service} {Scope.my.scope.attribute some scope attribute} {Scope.name my.library} {Scope.version 1.0.0} {SeverityNumber 10} {SeverityText Information} {SpanId eee19b7ec3c1b174} {TraceFlags 0} {TraceId 5b8efff798038103d269b633813fc60c}]

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: pre-calculate hashes from tokens used in bloom filter search
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()`.

lib/logstorage: properly fix incorrect extraction of common tokens for OR filters at distinct log fields
Previously (f1:foo OR f2:bar) was incorrectly returning `foo` token for `f1` and `bar` token for `f2`.
These tokens were used for checking against bloom filter for every data block, so the data block,
which didn't contain simultaneously `foo` token for `f1` field and `bar` token for `f2` field, was skipped.
This was incorrect, since such a block may contain logs matching the original OR filter.

The fix is to return common tokens from `OR`-delimted filters only if these tokens exist at EVERY such filter
for the given field name. If some `OR`-delimited filter misses the given field name, then `OR`-delimited filters
do not contain common tokens, which could be used for checking against bloom filter.

While at it, add more tests covering various edge cases for filters delimited by AND and OR.
