[SPARK-23938][SQL][FOLLOW-UP][TEST] Nullabilities of value arguments should
be true.
## What changes were proposed in this pull request?
This is a follow-up pr of #22017 which added `map_zip_with` function.
In the test, when creating a lambda function, we use the
`valueContainsNull` values for the nullabilities of the value arguments, but we
should've used `true` as the same as `bind` method because the values might be
`null` if the keys don't match.
## How was this patch tested?
Added small tests and existing tests.
