What this PR does

This PR makes all changes required to bring MQE into line with Prometheus 3's behaviour.

This PR is blocked by two bugfixes currently pending review from the Prometheus team:

If we want to unblock the upgrade, we could cherry-pick these fixes into mimir-prometheus.

This PR depends on prometheus/prometheus#15245 being pulled into mimir-prometheus.

This PR is also blocked pending confirmation of the expected behaviour of subqueries with the change to left-open intervals for range queries: prometheus/prometheus#15412 (this is why TestSubqueries is currently failing)

This PR builds upon #9844.

Which issue(s) this PR fixes or relates to
