Track based on JSArrayBuffer addresses on pages instead of the attached
backing store.
Details of tracking:
- Scavenge: New space pages are processes in bulk on the main thread
- MC: Unswept pages are processed in bulk in parallel. All other pages
are processed by the sweeper concurrently.

Track based on JSArrayBuffer addresses instead of the attached backing store.
This way we can later on iterate buffers on a single page. The reland also
switches to a page-based implementation where a page contains the set of its
contained (live and dead) buffers.
Details of tracking:
- Scavenge: New space pages are processes in bulk on the main thread
- MC: Unswept pages are processed in bulk in parallel. All other pages
are processed by the sweeper concurrently.
