Use CopyTo when resetting histogram in stats iterator
The histogram stats iterator does not fully clear the histogram object
and is not resilient to new fields being added to the histogram type.

To resolve the issue, the commit uses the CopyTo methods which should
be future proof to new fields being added.

Ignore stale histograms for counter reset detection
The histogram stats decoder keeps track of the last seen histogram sample
in order to properly detect counter resets. We are seeing an issue where
a histogram with UnknownResetHint gets treated as a counter reset when it follows
a stale histogram sample.

I believe that this is incorrect since stale samples should be completely ignored
in PromQL. As a result, they should not be stored in the histogram stats iterator
and the counter reset detection needs to be done against the last non-stale sample.

Allow built-in tests to be customized
The RunBuiltinTests function accepts a concrete type which makes
it hard to exclude certain tests from the suite. It would be great
if we could skip tests which might not be critical in order to unblock
updates.

By accepting an interface instead, we can inject a custom implementation
which would skips select test cases.

Fix decoding buckets for native histograms in binops
The optimizer which detects cases where histogram buckets can be skipped
does not take into account binary expressions. This can lead to buckets
not being decoded if a metric is used with both histogram_fraction/quantile and
histogram_sum/count in the same expression.

Implement histogram statistics decoder (#14097)
Implement histogram statistics decoder

This commit speeds up histogram_count and histogram_sum
functions on native histograms. The idea is to have separate decoders which can be
used by the engine to only read count/sum values from histogram objects. This should help
with reducing allocations when decoding histograms, as well as with speeding up aggregations
like sum since they will be done on floats and not on histogram objects.
