This reverts commit 584f0b43.

Reason for revert: Breaks MSAN build - https://ci.chromium.org/p/v8/builders/luci.v8.ci/V8%20Linux%20-%20arm64%20-%20sim%20-%20MSAN/24872

Original change's description:
> [api, global-handles] Fix moving weak Global<T>
> 
> v8::Global may be used as a weak reference. In the case this reference is a
> simple phantom reference, we need to update the internal state to be able to
> clear the right slot once the object refered to is dead.
