core: remove redundant storage of transactions and receipts (#14801)
* core: remove redundant storage of transactions and receipts * core, eth, internal: new transaction schema usage polishes * eth: implement upgrade mechanism for db deduplication * core, eth: drop old sequential key db upgrader * eth: close last iterator on successful db upgrage * core: prefix the lookup entries to make their purpose clearer
