Bryan Boreham d0dee51aac scrape tests: check NaN values directly 
Normally, a NaN value is never equal to any other value. Compare sample
values via `Float64bits` so that NaN values which are exactly the same
will compare equal.

beorn7 86d7618d84 promql: Fix wrongly scoped range vectors 
Fixes #11708.

If a range vector is fixen in time with the @ modifier, it gets still
moved around for different steps in a range query. Since no additional
points are retrieved from the TSDB, this leads to steadily emptying
the range, leading to the weird behavior described in isse #11708.

This only happens for functions listed in `AtModifierUnsafeFunctions`,
and the only of those that takes a range vector is `predict_linear`,
which is the reason why we see it only for this particular function.

fix: PrometheusNotIngestingSamples label matching 
This alert will never return anything as the left side of the query has
the labels `[component, environment, instance, job, type]` while the
right side has `[component, environment, instance, job]`.

The `type` label was added to `prometheus_tsdb_head_samples_appended_total` in this PR but the mixin wasn't updated
for the new label: https://github.com/prometheus/prometheus/pull/11395

Bryan Boreham 14b4fbc2ff labels: make InternStrings a no-op for stringlabels version 
The current implementation of `InternStrings` will only save memory
when the whole set of labels is identical to one already seen, and this
cannot happen in the one place it is called from in Prometheus,
remote-write, which already detects identical series.
