This creates a new TryBatchInsert function in trie. All key-value insertion
pairs are passed together. If the resolved root node is a full node, the
insertion pairs are partitioned by the first byte in their keys. Children
subtries of the full node are inserted in parallel. If the resolved root node is
not a full node, the insertion pairs are inserted sequentially.

When there are more than parallelInsertThreshold (currently set to 500) pending storages update to storage trie, we will use the new TryBatchInsert to parallel insert these storages if possible.
This benchmark is intended to be used with mainnet data. The benchmark includes many storage updates to Axie contract's storage.
