This improves performance for analytical queries, which do not need column headers metadata.
For example, the following query doesn't need column headers metadata, since _stream and min(_time)
are stored in block header, which is read separately from colum headers metadata:
_time:1w | stats by (_stream) min(_time) min_time
This commit significantly improves the performance for this query.

* `remoteWrite.maxQueueSize` from `100_000` to `1_000_000`, this should
improve resiliency of recording rules that produce many series;
* `remoteWrite.maxBatchSize` from `1_000` to `10_000`, this should be
more efficient to send from netwroking perspective;
* `remoteWrite.concurrency` from `1` to `4`, this should imrpove speed
of sending the generated series.
The new settings should improve remote write performance of vmalert with
default settings.

(cherry picked from commit 6b1b47df54)
Substitute global streamTagsCache with per-blockSearch cache for ((stream.id) -> (_stream value)) entries.
This improves scalability of obtaining _stream values on a machine with many CPU cores, since every CPU
has its own blockSearch instance.
This also should reduce memory usage when querying logs over big number of streams, since per-blockSearch
cache of ((stream.id) -> (_stream value)) entries is limited in size, and its lifetime is bounded by a single query.
The change supposed to have more practical recommendations and reflect
the real processes for maintaining the project.

The streamID.marshalString() is executed in hot path if the query selects _stream_id field.
Command to run the benchmark:
go test ./lib/logstorage/ -run=NONE -bench=BenchmarkStreamIDMarshalString -benchtime=5s
Results before the commit:
BenchmarkStreamIDMarshalString-16 438480714 14.04 ns/op 71.23 MB/s 0 B/op 0 allocs/op
Results after the commit:
BenchmarkStreamIDMarshalString-16 982459660 6.049 ns/op 165.30 MB/s 0 B/op 0 allocs/op
This test is very flaky and prevents other tests from running in CI.
Disabling this test should improve tests quality, since it isn't reliable anyway.
There is a ticket to fix this test - https://github.com/VictoriaMetrics/VictoriaMetrics/issues/7062
Once fixed, this test should be uncommented.

By default, the `elasticsearchexporter` in OTel Collector puts the log

(cherry picked from commit 91b28d0527)
Rounding GOMAXPROCS to the upper interger value of cpuQuota increases chances of CPU starvation,
non-optimimal goroutine scheduling and additional CPU overhead related to context switching.
So it is better to round GOMAXPROCS to the lower integer value of cpuQuota.
It is expected that range_first and range_last functions return non-nan const value across all the points
if the original series contains at least a single non-NaN value. Previously this rule was violated for NaN data points
in the original series. This could confuse users.
While at it, add tests for series with NaN values across all the range_* and running_* functions, in order to maintain
consistent handling of NaN values across these functions.

The previous behaviour was incorrect, since it is unexpected that the -streamAggr.dedupInterval
and -remoteWrite.streamAggr.dedupInterval is applied to processed samples only if -streamAggr.config isn't set.

### Describe Your Changes
Currently it the metricID list is empty it won't be mashalled and as the
result won't be put into the tagFiltersToMetricIDsCache which causes the
cache misses for the corresponding tagFilters. In some setups this
causes severe search speed detradation (see #7009).
The empty metric IDs was covered before but then was accidentally
removed in 6c21439.
This PR restores the coverage of this case.
A new unit test can be used as a proof that empty metricID lists are not
added to the cache (just remove the fix in index_db.go and run the test
to see the result)
Also a benchmark has been added to see the implications of the
compression.

The indexSearch.containsTimeRange() function is called for the current indexDB and the previous indexDB
every time when searching for metricIDs by label filters. This function consumes a lot of additional CPU time
for cases when queries with lightweight label filters are sent to VictoriaMetrics at high rate (e.g. thousands of RPS),
like in the issue https://github.com/VictoriaMetrics/VictoriaMetrics/issues/7009 .
Optimize indexSearch.containsTimeRange() function in the following ways:
- Unconditionally return true if this function is called for the current indexDB, since there are very high
chances that the current indexDB contains the data with timestamps in the requested time range.
- Cache the minimum timestamp, which is missing in the indexed data for the previous indexDB.
This is safe to do, since the previous indexDB is readonly.
This optimization eliminates potentially slow lookup in the previous indexDB for typical
use cases when the requested time range is close to the current time.
Previously indexDB.doExtDB() was returning boolean value, which was indicating whether f callback was called.
There is no need in returning this boolean value, since the f callback can determine on itself whether it was called.
This simplifies the code a bit.
While at it, document indexDB.doExtDB().
Make function name and comments more clear.
