Improve the perf for pool item scanning..

for large complex documents with lots of shapes.

When that happens, we spend a lot of time scanning the std::unordered_set inside DefaultItemInstanceManager.

Since most of our items are already capable of being hashed, and thus avoiding the scanning cost, make it so we can use the HashableItemInstanceManager most of the time.
