[FLINK-7461] Remove Backwards compatibility with <= Flink 1.1
## Brief change log
This PR removes backwards compatibility with Flink <= 1.1 from the code. In particular, we can remove many special cases, such as the non-partitionable state that was created by the `Checkpointed` interface (replaced by `CheckpointedFunction` in 1.2).
We also drop aligned windows, which have already been a "hidden feature" since 1.2, because they still rely on the outdated `Checkpointed` interface.
The `Checkpointed` and `CheckpointedRestoring` interfaces are also removed and all related test cases have either been deleted or adapted.

> This issue tracks the removal of Flink 1.1 backwards compatibility from Flink 1.4. This step is helpful for further developments because it will remove many old code paths and special cases. In particular, we can drop all handling for non-partitionable state, i.e. state that was created with the old {{Checkpointed}} interface.
