[FLINK-22574] Adaptive Scheduler: Fix cancellation while in Restarting state.

The Canceling state of Adaptive Scheduler was expecting the ExecutionGraph to be in state RUNNING when entering the state.
However, the Restarting state is cancelling the ExecutionGraph already, thus the ExectionGraph can be in state CANCELING or CANCELED when entering the Canceling state.

Calling the ExecutionGraph.cancel() method in the Canceling state while being in ExecutionGraph.state = CANCELED || CANCELLED is not a problem.

The change is guarded by a new ITCase, as this issue affects the interplay between different AS states.

This closes #15882
