5e282808 - remove unstable_forceStale prefetch option & restore `prefetch={true}` functionality (#85411)

remove unstable_forceStale prefetch option & restore `prefetch={true}` functionality (#85411) `prefetch={true}` with `cacheComponents` was opting into runtime prefetching, with `unstable_forceStale` preserving the old behavior of fetching the full (stale) data. However we only intended to expose runtime prefetching via the `export const prefetch` segment config. This removes `unstable_forceStale` and restores previous `prefetch={true}` behavior. I've disabled some of the tests that were relying on the old link behavior for opting into runtime prefetching - we'll need to refactor those to use the segment opt-in or just remove them all together. Fixes #85162 Closes NAR-320
