[FLINK-37701][flink-runtime] Backporting of the fix to 2.0 for AdaptiveScheduler ignoring checkpoint states sizes for local recovery adjustment.

[Izeren]

Previously merged PRs:

• [FLINK-37701][flink-runtime] Fix AdaptiveScheduler ignoring checkpoint states sizes for local recovery adjustment. #26663
• [FLINK-37701] Cleanup after #26663 #26712

PR1 #26663

What is the purpose of the change

Address local recovery issues when Adaptive scheduler is enabled.

1. Pass latest completed checkpoint in addition to execution graph to StateSizeEstimates (that is needed because execution graph goes through cancelling/cancelled state and checkpoint coordinator is nulled by the time we run calculations).
2. Assign positive priority score to allocations that have overlapping key groups even when state size is zero (currently we would only give priority score if managedKeyedState is present, but local recovery semantics doesn't require state presence).

Context: When job can be recovered locally, we should keep slot allocation after restart to maintain

Verifying this change

LocalRecoveryITCase#testRecoverLocallyFromProcessCrashWithWorkingDirectory now passes when AdaptiveScheduler is enabled.
