Now that we've switched to the simple handling, the first thing that can be massively simplified is checkpoint deletion. We now need to only go through the backing chain and find the appropriately named bitmaps and delete them, no complex lookups or merging. Note that compared to other functions this deletes the bitmap in all layers compared to others where we expect only exactly 1 bitmap of a name in the backing chain to prevent potential problems.
