Wenchen Fan 974f524992 [SPARK-26798][SQL] HandleNullInputsForUDF should trust nullability
## What changes were proposed in this pull request?

There is a very old TODO in `HandleNullInputsForUDF`, saying that we can skip the null check if input is not nullable. We leverage the nullability info at many places, we can trust it here too.

## How was this patch tested?

re-enable an ignored test

Closes #23712 from cloud-fan/minor.
