deps: backport aa6ce3e from upstream V8

Original commit message:

    [log][api] introduce public CodeEventListener API

    Introduce a new public API called CodeEventListener to allow
    embedders to better support external profilers and other diagnostic
    tools without relying on unsupported methods like --perf-basic-prof.
