[SPARK-3681] [SQL] [PySpark] fix serialization of List and Map in SchemaRDD

Currently, the schema of object in ArrayType or MapType is attached lazily, it will have better performance but introduce issues while serialization or accessing nested objects.

This patch will apply schema to the objects of ArrayType or MapType immediately when accessing them, will be a little bit slower, but much robust.
