Returns total amount of output buffer memory for each device (CPU/GPU)

Columnar: if projection: it returns index buffer + columnar buffer (all non-lazy columns) if group by: it returns the amount required for each group column (assumes 64-bit per group) + columnar buffer (all involved agg columns)

Row-wise: returns required memory per row multiplied by number of entries
