[Feature Request]: Add OrderedListState test in StateInternalsTest

[twosom]

What would you like to happen?

As the number of state operators in Apache Beam grows, we need to update the existing StateInternalsTest.

Currently, tests exist for ValueState, BagState, SetState, MapState, CombiningValueState, and WatermarkHoldState, but not for MultiMapState and OrderdListState, which were added later.
