Stop-the-world compaction phase
The CL implements the core logic for per-page compaction, but in
a stop-the-world pause. Even though it's performed during a pause, it
handles every page independetly as the final goal is to have a
concurrent implementation.
This CL doesn't handle updating the native roots. Also, the black
allocations since the marking-phase pause are not handled yet.
