deps: V8: cherry-pick 25902244ad1a

Original commit message:

    [api] add line breaks to the output of Message::PrintCurrentStackTrace

    Previously this prints the stack trace without line breaks and it
    can be difficult to read. This also affects
    --abort-on-uncaught-exception. This patch adds line breaks to the
    output to improve readability.
