Optimize label values with matchers by taking shortcuts (#13426) 
Don't calculate postings beforehand: we may not need them. If all
matchers are for the requested label, we can just filter its values.

Also, if there are no values at all, no need to run any kind of
logic.

Also add more labelValuesWithMatchers benchmarks
