storage: Removed SelectSorted method; Simplified interface; Added requirement for remote read to sort response.

Browse source 
This is technically BREAKING CHANGE, but it was like this from the beginning: I just notice that we rely in
Prometheus on remote read being sorted. This is because we use selected data from remote reads in MergeSeriesSet
which rely on sorting.

I found during work on https://github.com/prometheus/prometheus/pull/5882 that
we do so many repetitions because of this, for not good reason. I think
I found a good balance between convenience and readability with just one method.
Smaller the interface = better.

Also I don't know what TestSelectSorted was testing, but now it's testing sorting.
