Use simpler schema when writing transactions, receipts, and withdrawals (#2420)
* Use simpler schema when writing transactions, receipts, and withdrawals

Using MPT not only slow but also take up more spaces than needed.
Aristo will remove older tries and only keep the last block tries.
Using simpler schema will avoid those problems.

* Rename getTransaction to getTransactionByIndex
