Maya Lekova 8b9d0138b3 Revert "cppgc: Rework GC info creation"
This reverts commit d76064df4f.

Reason for revert: Breaking MSAN - https://ci.chromium.org/ui/p/v8/builders/ci/V8%20Linux%20-%20arm64%20-%20sim%20-%20MSAN/37390/overview

Original change's description:
> cppgc: Rework GC info creation
>
> Previously, GCInfoTrait relied on the non-trivial constructor of a
> static object for registering a new GCInfo object. The generated code
> is required to be thread-safe which is achieved by introducing guard
> variables in the compiler.
>
> The new version is similar to Blink in that it relies on zero
> initialization of a trivially constructible atomic.
>
> Compared to guard variables that are created per GCInfo registration,
> the atomic creates less bloat (~20bytes/type) and also results in a
> better fast path.
>
> Minimum example: https://godbolt.org/z/qrdTf8
>
