[SPARK-25457][SQL] IntegralDivide returns data type of the operands
## What changes were proposed in this pull request?
The PR proposes to return the data type of the operands as a result for the

a `spark.sql.legacy.integralDivide.returnBigint` config in order to let the
users restore the legacy behavior.
## How was this patch tested?
added UTs
