[HUDI-3720] Fix the logic of reattempting pending rollback

[yihua]

What is the purpose of the pull request

When reattempting a pending rollback and the instant to rollback does not exist in the active timeline anymore due to a failure just before the rollback was transitioned from inflight to complete, such rollback cannot successfully be completed. This PR fixes the logic so that in such case the rollback can be reattempted successfully.

Brief change log

• Changes how the rollback is executed in different scenarios in BaseHoodieWriteClient.
• Adds unit tests in TestClientRollback.

Verify this pull request

This change added tests in TestClientRollback and is verified as follows:

• Run deltastreamer continuous mode writing MOR table. Fail the deltastreamer and a rollback before markers are deleted or just before the rollback is transitioned from inflight to complete. Rerun the deltastreamer. Verified that the same rollback can finish successfully (which was failing to retry before this change), markers are deleted, and the rollback metadata is correct.
