PERF: introduce site/global emoji cache (#15899)
Previously calls such as `Emoji["smile"]` would force a full dehydration of
objects from Redis.

This introduces a version safe site and global emoji cache so lookups are
cheap. It eliminates iterating through the list of emojis and pulling from
redis.

Distributed cache uses a normalized name as the key and stores an Array tuple
with version and Emoji. Successful hits always confirm version matches.

Interface to Emoji object remains unchanged.

We opted for 2 caches to improve reuse on multisites. misses though will be
stored in both caches. If there is a hit on the global cache we can avoid
looking up in site local cache and storing a miss there.
