step() is a new keyword introduced to represent the query step width in duration expressions.
min(a,b) and max(a,b) return the min and max from two duration expressions.

This requires a bit of repetition to cover all the different builds, but
it seems worth checking that the function does what is expected.

This commit brings back direct mean calculation (for `avg` and
`avg_over_time`) but isn't an outright revert of #16569. It keeps the
improved incremental mean calculation and features generally a bit
cleaner code than before.
Also, this commit...
- ...updates the lengthy comment explaining the whole situation and
trade-offs.
- ...divides the running sum and the Kahan compensation term
separately (in direct mean calculation) to avoid the (unlikely)
possibility that sum and Kahan compensation together ovorflow
float64.
- ...uncomments the tests that should now work again on darwin/arm64.
- ...uncomments the test that should now reliably yield the
(inaccurate) value 0 on all hardware platforms. Also, the test
description has been updated accordingly.
- ...adds avg_over_time tests for zero and one sample in the range.

The test in question actually worked fine even before #16569. The
finding reported in the comment has turned out to be caused by
something else.

* OTLP receiver: Don't append _total suffix to non-monotonic OTel sums
Fix the OTLP receiver so the suffix _total isn't appended to metrics
converted from non-monotonic OTel sum metrics, if otlp.translation_strategy is
UnderscoreEscapingWithSuffixes or NoUTF8EscapingWithSuffixes.
Also add translation tests.

* fix(promql): histogram_quantile NaN observed in native histogram
Fixes: #16578
See the issue for detailed explanation.
When a histogram had only NaN observations and no normal observations,
we returned 0 from the quantile, which is completely wrong. If there were
normal observations but we went over them, we returned the upper bound of
the existing buckets, however that contradicts expectations on
histogram_fraction. Now we return NaN if the quantile is calculated to be
over all normal observations, falling into NaNs (in a virtual +Inf bucket).
We also return info level annotations if we see any NaN observations.
The annotation calls out if we returned NaN or even if we took the
virtual +Inf bucket into account.

* fix(promql): histogram_fraction NaN observed in native histogram
Fixes: #16580
According to the specification we should not take NaN observations
into account when calculating the fraction. This commit fixes that
and adds an info level annotation to let the user know about this.

We should use the configured value, or Prometheus' default of 75%, while
initializing and loading the WAL.
Since the Go default is 100%, most Prometheus users would experience
higher memory usage before the value is configured.

We need Prometheus to build with the last 2 versions of Go.
Remove Go toolchain line - it is redundant with the `go`` line above,
and could mislead readers.
Also don't update `fsnotify` which is pinned to an older version.
