### Is your feature request related to a problem or challenge?
Trying to create an ArrayRef from the following iterator:
|optional_value| {
optional_value.map(|value|
function_that_returns_scalar(value)).unwrap_or(ScalarValue::Null)
}
Since iter_to_array does not accept a DataType, it cannot work on nullable
lists,
having a null in the beginning of the iter will try and create a null array,
meaning following values will return an exec_err, having one in the middle will
try and create a value array and will return an error because a null was found
### Describe the solution you'd like
Have the actual building logic of the iter_to_array function moved to
another function, which accepts a datatype and nullability, and will not
consider null values to be a breach of that datatype, unless nullability is
false
the iter_to_array function can maintain the peek() logic, and pass it on to
the other function containing the build logic, with nullability set to false,
to maintain compatibility.
