When the scrape tolerance is bigger than 1% of the scrape interval, take
1% of the scrape interval as the tolerance instead of not aligning the
scrape at all.

This adds support for the new grammar of `{"metric_name", "l1"="val"}` to promql and some of the exposition formats.
This grammar will also be valid for non-UTF-8 names.
UTF-8 names will not be considered valid unless model.NameValidationScheme is changed.
This does not update the go expfmt parser in text_parse.go, which will be addressed by https://github.com/prometheus/common/issues/554/.

The old import path stopped working.
```
go get go.buf.build/protocolbuffers/go/prometheus/prometheus
go: unrecognized import path "go.buf.build/protocolbuffers/go/prometheus/prometheus": https fetch: Get "https://go.buf.build/protocolbuffers/go/prometheus/prometheus?go-get=1": dial tcp: lookup go.buf.build on 192.168.2.1:53: no such host
```
We should instead tell users to use the new import paths.

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.

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.

These functions act on the labels only, so don't need to go step by step
over the samples in a range query.
