Is always nice to see more usage of Fast APIs, thanks for the PR!

Not blocking but just a reminder - it would be faster if we just pass env->time_origin_timestamp() the same way we pass env->time_origin() to JS land via a typed array, and don't do a native call at all, because this is conceptually a constant (I am a bit surprised that it's not done already since we've been doing this for env->time_origin(), though with a closer look it seems to be only used by performance.nodeTiming.

Thanks for the suggestion @joyeecheung ! I've changed the code to pass env->time_origin_timestamp() the same way we do with env->time_origin(). It's now faster. Here is the benchmarks to show the improvement.

                                                        confidence improvement accuracy (*)   (**)  (***)
perf_hooks/time-origin.js method='timeOrigin' n=1000000        ***    120.57 %       ±2.46% ±3.30% ±4.35%
perf_hooks/time-origin.js method='toJSON' n=1000000            ***     32.10 %       ±1.64% ±2.18% ±2.86%

I've updated the commit message and PR title since it's no more a Fast api implementation, could you please review it again 🙏

LGTM % comments. The timestamp is already a double and there is no need to cast it to uint64_t on the way.
