[FLINK-5265] Introduce state handle replication mode for
CheckpointCoordinator
Currently, the ``CheckpointCoordinator`` only supports repartitioning of
``OperatorStateHandle``s based on a split-and-distribute strategy. For future
state types, such as broadcast or union state, we need a different
repartitioning method that allows for replicating state handles to all subtasks.
This functionality is introduced with this PR and represents the first step
on the way to implementing broadcast and union states.
