> Use skip scan when row value constructor uses leading row key columns

>
> We currently only use a skip scan for a row value constructor equality or in
> list expression is fully qualified. We can fairly easily use it when only
> some of the leading pk columns are used.
> For example:
> {code}
> WHERE (a,b) IN ((1,2),(3,4))
> {code}
> If the PK is (a,b,c), we can still use a skip scan. We need to pass through
> the slotSpan array in this case too, to the SkipScanFilter.
