Since the Target object was just created in this function, nobody else
has a reference to it and there are no concerns about it being modified
concurrently so we don't need to copy the value.

Includes a rewrite of `resolveConflictingExposedLabels` to use
`labels.Builder.Get`, which simplifies it considerably.

Although we had a different slice, the underlying memory was the same so
any changes meant we could skip some values.

Scraping targets are synced by creating the full set, then adding/removing any which have changed.
This PR speeds up the process of creating the full set.
I added a benchmark for `TargetsFromGroup`; it uses configuration from a typical Kubernetes SD.
The crux of the change is to do relabeling inside labels.Builder instead of converting to labels.Labels and back again for every rule. The change is broken into several commits for easier review.
This is a breaking change to `scrape.PopulateLabels()`, but `relabel.Process` is left as-is, with a new `relabel.ProcessBuilder` option.
In storage/remote, try converting to RecoverableError using errors.As,
instead of through direct casting.

TestConcurrentRangeQueries runs many queries, up to 4 at the same time,
to try to expose any race conditions.
This change stops four of them from running with a thousand or more steps:
`holt_winters(a_X[1d], 0.3, 0.3)`
`changes(a_X[1d])`
`rate(a_X[1d])`
`absent_over_time(a_X[1d])`
Particularly when the test runs with `-race` in CI, this reduces the
time and resources required.
