deps: cherry-pick f19b889 from upstream V8

Original commit message:

    [inspector] support for cases when embedder doesn't call contextDestroyed

    Node.js doesn't have good place to call contextDestroyed.
    We need to cleanup everything on our side to allow clients to not call
    contextDestroyed method.
