Function fused_window_aggr

fn fused_window_aggr<'a, I, A>(
    input_datums: I,
    callers_temp_storage: &'a RowArena,
    wrapped_aggregates: &Vec<AggregateFunc>,
    order_by: &Vec<ColumnOrder>,

Computes a bundle of fused window aggregations. The input is similar to window_aggr, but InputValue is not just a single value, but a record where each component is the input to one of the aggregations.
