Fix: Prefetching lazily generated param

[acdlite]

Fixes an oversight in #72168 where the segment data was not correctly transferred from the render result to the cache entry in the case where a prerender is lazily generated after build.

I also took the opportunity to remove one of the intermediate types used by the various layers that the segment data passes through. For some reason, in the original PR I made the type of segmentData on CachedAppPageValue an object while the corresponding type on AppPageRenderResultMetadata was a map. (I didn't really notice before because in the case where the entry is generated at build time, it gets written to disk then read back out, so there's some data conversion happening anyway.)
