pick: #42256
Add a trait PropagateNullLiteral, which ensures that if any of its input
parameters is a null literal, the output will also be a null literal. Note that
PropagateNullable also has this property. Due to limitations in the
GeneratedExpressionRelations map, most functions that implement alwaysNullable
are included in PropagateNullLiteral. Therefore, defining a function that is
PropagateNullable but not PropagateNullLiteral is not currently allowed.
