### 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.

* Previously, only metricID->metricName missing index records were
tracked with deadline But it was possible a case for missing
metricID->TSID index records. IndexDB metrics fix exposed misleading
metric for such missing records.
* This commit adds check for metricID->TSID missing index records. And
delete missing metricID entry if it hit 60 second deadline.

Previously we manually imported system windows DDLs
and made direct syscall.
But golang exposes syscall wrappers with sys/windows package.
It seems, that direct syscall was broken at 1.23 golang release. It was
`GetDiskFreeSpace` syscall in our case.
This commit replaces all manual syscalls with wrappers

…pair
`alert_relabel_configs` in [notifier
config](https://docs.victoriametrics.com/vmalert/#notifier-configuration-file)
can drop alert labels when used to filter different tenant alert message
to different notifier.
alertmanager would report error like `msg="Failed to validate alerts"
err="at least one label pair required"` in this case, but the rest of
the alerts inside one request would still be valid in alertmanager, so
it's not severe.
