Add object packing strategies for compaction
This commit adds an alternative packing strategy for compaction.
Instead of packing towards "most pinned" pages, we can pack towards
"most empty" pages. The idea is that we can double the heap size, then
pack all objects towards the empty side of the heap. This will ensure
maximum chaos for testing / verification.
