Move partition_index_cache stats from a thread_local variable to cache_tracker. After the change, partition_index_cache receives a reference to the stats via constructor, instead of referencing a global. This is needed so that cache_tracker can know the memory usage of index caches (for cache eviction purposes) without relying on globals. But it also makes sense even without that motive.
