[fix](cloud-mow) MS should delete the existing keys before rewriting it when processing old version delete bitmap on cu compaction

[hust-hhb]

pr #40204 support deleting old version delete bitmap when doing cu compaction, it will update delete bitmap with agg result, then deleting old version delete bitmap. Updating delete bitmap means overwriting existing keys, however delete bitmap may split into multiple kvs to store in fdb, so we should delete the existing keys and rewrite it to fdb instead of overwriting directly.
pick pr #42379
