Bryan Boreham 2cf3c9de8f promql: store labels per-group only for count_values 
This saves memory in other kinds of aggregation.

We don't need `orderedResult` in `aggregationCountValues`; the ordering
is not guaranteed.

This is a cleaner split of responsibilities.

Bryan Boreham 29244fb841 promql: refactor: extract count_values implementation 
The existing aggregation function is very long and covers very different
cases.

`aggregationCountValues` is just for `count_values`, which differs from
other aggregations in that it outputs as many series per group as there
are values in the input.

Remove the top-level switch on string parameter type; use the same `Op`
check there as elswehere.

Pull checking parameters out to caller, where it is only executed once.
