luluorta cbd3fdea62 [SPARK-33008][SQL] Division by zero on divide-like operations returns incorrect result
### What changes were proposed in this pull request?
In ANSI mode, when a division by zero occurs performing a divide-like operation (Divide, IntegralDivide, Remainder or Pmod), we are returning an incorrect value. Instead, we should throw an exception, as stated in the SQL standard.

### Why are the changes needed?
Result corrupt.

### Does this PR introduce any user-facing change?
No.

### How was this patch tested?
added UT + existing UTs (improved)

Closes #29882 from luluorta/SPARK-33008.
