MCOL-4188 Regression fixes for MCOL-641.

Browse Source 
1. In TupleAggregateStep::configDeliveredRowGroup(), use
jobInfo.projectionCols instead of jobInfo.nonConstCols
for setting scale and precision if the source column is
wide decimal.

2. Tighten rules for wide decimal processing. Specifically:
  a. Replace (precision > INT64MAXPRECISION) checks with
     (precision > INT64MAXPRECISION && precision <= INT128MAXPRECISION)
  b. At places where (colWidth == MAXDECIMALWIDTH) is not enough to
     determine if a column is wide decimal or not, also add a check on
     type being DECIMAL/UDECIMAL.
