61926bae01 app/vmselect/promql: adjust the provided window only for range functions with dt in denominator
This should fix range function calculations such as `changes(m[d])` where `d` is smaller
than the scrape interval.

9e1119dab8 app/vmselect/promql: ajdust data model to the model used in Prometheus
Do not take into account data points on the range `[timestamp .. timestamp+step)`
when calculating value on the given `timestamp`.
Use only data points from the past when performing these calculations like Prometheus does.

This should reduce discrepancies between results returned by VictoriaMetrics
and results returned by Prometheus.
