Fix last_over_time for native histograms
The last_over_time retains a histogram sample without making a copy.
This sample is now coming from the buffered iterator used for windowing functions,
and can be reused for reading subsequent samples as the iterator progresses.

I would propose copying the sample in the last_over_time function, similar to
how it is done for rate, sum_over_time and others.

Unit tests for native histograms (#12668)
promql: Extend testing framework to support native histograms

This includes both the internal testing framework as well as the rules unit test feature of promtool.

This also adds a bunch of basic tests. Many of the code level tests can now be converted to tests within the framework, and more tests can be added easily.
