Revert of [heap] Better integrate handling of aborted compaction pages (patchset #7 id:130001 of https://codereview.chromium.org/1881423003/ )

Original issue's description:
> [heap] Better integrate handling of aborted compaction pages

> - Get rid of sweeping on the main thread
>
> Instead:
> - Record (and process afterwards) slots in parallel
> - Add the pages to the concurrent sweeper as pointers have already been fixed
