Add Divide and multiple interval expressions as supported

[nartal1]

This contributes to #865

DivideDTInterval and DivideDMInterval are divide operation of interval type by numeric. These are selected based on the type of input for "Divide" operator in Analyzer - link.

        case d @ Divide(l, r, mode) if d.childrenResolved => (l.dataType, r.dataType) match {
          case (CalendarIntervalType, _) => DivideInterval(l, r, mode == EvalMode.ANSI)
          case (_: YearMonthIntervalType, _) => DivideYMInterval(l, r)
          case (_: DayTimeIntervalType, _) => DivideDTInterval(l, r)
          case _ => d
        }

So we would not see any new expression rather it would be a Divide expression in the eventlog.
It's similar for Multiplication of Interval types by numeric (MultiplyDTInterval, MultiplyYMInterval).
Added these are supported for completion and removed from override_config_supported.json file.
Adding scores is not required for these expressions as it would be covered by "Divide" expression.

Thanks @nartal1
Yes, I think we don't need to do more than this.
