What this PR does
This PR is a small optimisation for instant vector selectors in MQE.
Previously, instant vector selectors would always use a slice with capacity for the number of steps in the range query.
However, if a series only has samples beginning part-way through the query range, this is wasteful: we know the series can't have more samples than remain in the query range, so we don't need such a big slice.
Which issue(s) this PR fixes or relates to
(none)
