IndexingMemoryController should not track shard index states
This commit modifies IndexingMemoryController to be stateless. Rather than statefully tracking the indexing status of shards, IndexingMemoryController can grab all available shards, check their idle state, and then resize the buffers based on the number of and which shards are not idle. The driver for this change is a performance regression that can arise in some scenarios after #13918. One scenario under which this performance regression can arise is if an index is deleted and then created again. Because IndexingMemoryController was previously statefully tracking the state of shards via a map of ShardIds, the new shards with the same ShardIds as previously existing shards would not be detected and therefore their version maps would never be resized from the defaults. This led to an explosion in the number of merges causing a degradation in performance. Closes #15225
