Add `whenInViewContext` higher-order component (HOC) to allow simplification of code that should only run inside some view contexts about site-kit-wp

@benbowler Adding invariant checks makes sense, let's do that too 👍🏻

Also, while it wasn't in the ACs, let's add it to at least one component so we can QA it properly 👍🏻 I've added refactoring [GA4AdSenseLinkedNotification.js](https://github.com/google/site-kit-wp/blob/4cce042da8831b2ec8663e4d9767bc0610ae4e5a/assets/js/components/notifications/GA4AdSenseLinkedNotification.js#L115-L121) to the ACs 🙂

Created the IB. Some possible additions/questions:

• We could add something like invariant if the user passes invalid prop combinations like both and include and exclude list or both view only and non view only?
• I assumed we weren't using this new HOC yet in this ticket? Otherwise we could add a case/some cases to refactor as part of this work.

Looks good to me 👍🏻
