[ENHANCEMENT] TSDB: Optimize querying with regexp matchers

Add method `PostingsForLabelMatching` to `tsdb.IndexReader`, to obtain postings for labels with a certain name and values accepted by a provided callback, and use it from `tsdb.PostingsForMatchers`.
The intention is to optimize regexp matcher paths, especially not having to load all label values before matching on them.

Plus tests, and refactor some `tsdb/index.Reader` methods.

Benchmarking shows memory reduction up to ~100%, and speedup of up to ~50%.
