Fix MERGE command tag for actions blocked by BEFORE ROW triggers.
This ensures that the row count in the command tag for a MERGE is
correctly computed in the case where UPDATEs or DELETEs are skipped
due to a BEFORE ROW trigger returning NULL (the INSERT case was
already handled correctly by ExecMergeNotMatched() calling
ExecInsert()).
Back-patch to v15, where MERGE was introduced.
