[cfe] Special case Null in assignability errors.
...
In error reporting on assignability where the expression has type
`Null` we use a special messages that doesn't state that
"'Null' is nullable". Cases where `Null` is part of the type or where
the expression of type `Null` is derived from a collection are not
special cased.
