Title: Introduce a cache tied to individual sitemap pages

This helps individual extensions avoid having to implement methods to clear the cache whenever a page changes. I had hoped to use this for frontmatter, but the way it stores its information (and how its population of `:raw_template` interacts with the renderer) turned out too be complicated - I'll leave that for another time.
