SD-129 Mark JFunctionN as serializable

Before this change, if these were used as the target type of a lambda
in Java source code, the lambda would not be serializable. This is
somewhat suprising when contrasted with the way that Scala lambdas
work in Scala source.

Since we copied these classes over from scala-java8-compat, that
project has opted to add Serializable as a parent to solve this issue.
This commit brings our copy of these interfaces into line with that
change.
