I am actually not sure if we should use constants (e.g. strings) for these, suggestions are welcome. Also AFAIK exposeInternals doesn't currently change anything for us because we don't use any embedder tracing mechanism provided by V8 that could would make a difference here, but this might change in the future.

Updated to use destructuring + default values because assignment doesn't work with kEmtpyObject. @jasnell @aduh95

@joyeecheung this broke when landing in v18.x-staging. Do you mind opening a backport PR for this?
