Thomas Jackson a000cec011 Re-use label builder in promql aggregation (#5641)
For my benchmarks on aggregation this reduces allocations by ~5% (~10%
time improvement):

```
benchmark                                                    old ns/op     new ns/op     delta
BenchmarkEvaluations/benchdata/aggregators.test/promxy-4     727692        649626        -10.73%

benchmark                                                    old allocs     new allocs     delta
BenchmarkEvaluations/benchdata/aggregators.test/promxy-4     2566           2434           -5.14%

benchmark                                                    old bytes     new bytes     delta
BenchmarkEvaluations/benchdata/aggregators.test/promxy-4     162760        148854        -8.54%
```
