Auto merge of #70674 - cjgillot:query-arena-all, r=matthewjasper
Have the per-query caches store the results on arenas This PR leverages the cache for each query to serve as storage area for the query results. It introduces a new cache `ArenaCache`, which moves the result to an arena, and only stores the reference in the hash map. This allows to remove a sizeable part of the usage of the global `TyCtxt` arena. I only migrated queries that already used arenas before.
