[FLINK-5790][StateBackend] Use list types when ListStateDescriptor extends
StateDescriptor
1. Now the state serializer, instead of the element serializer, is stored
in `ListStateDescriptor`.
2. `ArrayListTypeInfo` is introduced to help create serializers with the
element type.
3. `ArrayListSerializer` is moved to the package
org.apache.flink.api.common.typeutils.base to avoid cyclic dependencies.
4. Old implementation of `ListStateDescriptor` is kept in the migration
package for back compatibility.
