lib/storage: improve performance for indexSearch.containsTimeRange() 
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.
