Revert of Reland "[heap] Fine-grained JSArrayBuffer tracking" (patchset #7 id:180001 of https://codereview.chromium.org/2026633003/ )

Reason for revert:
Also failing with the new implementation:
  https://build.chromium.org/p/chromium.gpu/builders/Linux%20Debug%20%28NVIDIA%29/builds/62646

Will do a local repro now.

Original issue's description:
> 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.
