Protected pre-rendered routes

[hyunbinseo]

Describe the problem

I have an expensive static page which also happens to be a protected route.

I would love to prerender the page, but then it is not handled by SvelteKit.

Requests for static assets — which includes pages that were already prerendered — are not handled by SvelteKit.

https://kit.svelte.dev/docs/hooks#server-hooks-handle

Describe the proposed solution

1. Add another page option in +page|layout.server.ts such as server: true.
2. Add another value for the current prerender option such as protected.
3. (Breaking) Convert the page prerender option into an object?

type Prerender = { enabled: boolean; protected: boolean };

https://kit.svelte.dev/docs/page-options#prerender

I am sure there are other usage then protected, but it seemed the most intuitive.

Will be implemented in #13477

Unlike the handle hook, middleware runs on all requests, including for static assets and prerendered pages. If using server-side route resolution this means it runs prior to all navigations, no matter client- or server-side.
