[Impl](Nereids) add propagateNullLiteral trait for special functions (a…

…pache#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.
