[SPARK-12834] Change ser/de of JavaArray and JavaList
https://issues.apache.org/jira/browse/SPARK-12834
We use `SerDe.dumps()` to serialize `JavaArray` and `JavaList` in
`PythonMLLibAPI`, then deserialize them with `PickleSerializer` in Python side.
However, there is no need to transform them in such an inefficient way. Instead
of it, we can use type conversion to convert them, e.g. `list(JavaArray)` or
`list(JavaList)`. What's more, there is an issue to Ser/De Scala Array as I
said in https://issues.apache.org/jira/browse/SPARK-12780
