Speed up `@cachedList` (#13591)
This speeds things up by ~2x. The vast majority of the time is now spent in `LruCache` moving things around the linked lists. We do this via two things: 1. Don't create a deferred per-key during bulk set operations in `DeferredCache`. Instead, only create them if a subsequent caller asks for the key. 2. Add a bulk lookup API to `DeferredCache` rather than use a loop.
