Add test to prevent premature removal of conflict-relevant data. A test has been added to ensure that conflict-relevant data is not prematurely removed when a concurrent prepared transaction is being committed on the publisher.
This test introduces an injection point that simulates the presence of a prepared transaction in the commit phase, validating that the system correctly delays conflict slot advancement until the transaction is fully committed. Additionally, the test serves as a safeguard for developers, ensuring that the acquisition of the commit timestamp does not occur before marking DELAY_CHKPT_IN_COMMIT in RecordTransactionCommitPrepared.
