Redundant DB query in `starknet_getTransactionReceipt` after `Combined Layout`

[EgeCaner]

Description

Currently RPC starknet_getTransactionReceipt executes two query to fetch transaction and receipt. Tx ref and receipt ref. With combined layout for transactions and receipts, two query becomes redundant and we should implement accessor to fetch both with one query.
