…failure time when cumulative compaction dealing with delete rowset (#43466)" (#46117)

Before this PR, in cases where there is an alternating distribution of
data rowset -> delete rowset -> data rowset -> delete rowset, cumulative
compaction would only move the cumulative point forward to allow base
compaction to handle the delete rowset. Cumulative compaction itself
would not process the data and would return be marked as failure. This
would cause the compaction submission task process to pause for 5
seconds, impacting efficiency.

This PR modifies the return status to OK for such cases, which improves
the efficiency of the compaction submission task.
