mlippautz a43b732e0e Revert of Reland "[heap] Fine-grained JSArrayBuffer tracking" (patchset #2 id:20001 of https://codereview.chromium.org/2024063002/ )
Reason for revert:
Breaking
  http://build.chromium.org/p/client.v8/builders/V8%20Linux64%20-%20avx2/builds/7972

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.
>
