I'd like to kickstart a proper spec/docs for the #__PURE__ notation for easier reference as I see it always a bit unclear how it works.

So here I draft the basic version. Looking forward to your review and feedback!

Now in @rollupjs v3.24.0, `#__NO_SIDE_EFFECTS__` annotation is supported to mark function declarations as side-effects free. You might not need to add `#__PURE__` to every call anymore, while providing more optimized bundles!

Thanks a lot to @lukastaegert's great support and fast release!
