[SPARK-28201][SQL] Revisit MakeDecimal behavior on overflow
## What changes were proposed in this pull request? In SPARK-23179, it has been introduced a flag to control the behavior in case of overflow on decimals. The behavior is: returning `null` when `spark.sql.decimalOperations.nullOnOverflow` (default and traditional Spark behavior); throwing an `ArithmeticException` if that conf is false (according to SQL standards, other DBs behavior). `MakeDecimal` so far had an ambiguous behavior. In case of codegen mode, it returned `null` as the other operators, but in interpreted mode, it was throwing an `IllegalArgumentException`. The PR aligns `MakeDecimal`'s behavior with the one of other operators as defined in SPARK-23179. So now both modes return `null` or throw `ArithmeticException` according to `spark.sql.decimalOperations.nullOnOverflow`'s value. Credits for this PR to mickjermsurawong-stripe who pointed out the wrong behavior in apache#20350. ## How was this patch tested? improved UTs Closes apache#25010 from mgaido91/SPARK-28201.
