Revert "[Fetch] Use wrapper tracing to express references between wrappers"

This reverts commit 8057f58cb22579bc685efa50c579325ed047d51a.

Reason for revert: Crashing. See https://crbug.com/862440.

Original change's description:
> [Fetch] Use wrapper tracing to express references between wrappers
>
> BodyStreamBuffer has a ReadableStream instance, but because it's
> implemented in V8Extra we cannot holds it as a member (i.e., as a
> ScriptValue). Instead, we attach the value to the JS wrapper of the
> C++ object. This required us to maintain chains of wrappers,
> FetchEvent -> Request -> BodyStreamBuffer for example, manually.
>
> This CL replaces that mechanism with wrapper tracing.
>
