Shu-yu Guo bdf634f851 Revert "unified-young-gen: Trace cross-heap references" 
This reverts commit 43f03448d3.

Reason for revert: Data race caught by TSAN:
https://ci.chromium.org/ui/p/v8/builders/ci/V8%20Linux64%20TSAN%20-%20isolates/22640/overview

Original change's description:
> unified-young-gen: Trace cross-heap references
>
> The CL enables the marking visitor in CppGC to trace
> v8::TracedReferences (by just reusing the unified heap visitor from the
> full GC). In addition, it specifies VisitJSApiObject for
> NewSpaceVisitors to be able to trace wrappers from Minor MC in case
> --cppgc-young-generation is enabled.
