1. [PERF] TSDB: Optimize inverse matching (#14144) …

   Simple follow-up to #13620. Modify `tsdb.PostingsForMatchers` to use the optimized tsdb.IndexReader.PostingsForLabelMatching method also for inverse matching.
   
   Introduce method `PostingsForAllLabelValues`, to avoid changing the existing method.
   
   The performance is much improved for a subset of the cases; there are up to
   ~60% CPU gains and ~12.5% reduction in memory usage.
   
   Remove `TestReader_InversePostingsForMatcherHonorsContextCancel` since
   `inversePostingsForMatcher` only passes `ctx` to `IndexReader` implementations now.
