feat: Implement trace_transaction

[Boreas09]

Provides transaction processing of type trace for the specified transaction. Use this API to improve smart contract performance by analyzing its internal transactions and execution steps. You can use this information to identify bottlenecks and optimize the contract for better performance.

Parameters :

transaction hash: [Required] The transaction hash

Returns :

A list of traces in the order called by the transaction.

@Boreas09 I’m available to work on this

[Boreas09]

This rpc-call can be fit to starknet_simulateTransactions. In ethereum call we just need to give a transaction hash. With that transaction hash we can call eth_getTransactionByHash and take values we need. Convert it to starknet and call starknet_simulateTransactions with simulation flags of SKIP_VALIDATE, SKIP_FEE_CHARGE. Finally convert starknet response to ethereum response. Return response.

@Boreas09 Is this open?
