feat: restructuring Part6 transaction crate

[rakita]

Introduction of Transaction trait and revm-transaction crate.

pub trait Transaction {
    /// An error that occurs when validating a transaction.
    type TransactionError: TransactionError;
    /// Transaction type.
    type TransactionType: Into<TransactionType>;
    /// Access list type.
    type AccessList: AccessListTrait;

    type Legacy: LegacyTx;
    type Eip2930: Eip2930Tx<AccessList = Self::AccessList>;
    type Eip1559: Eip1559Tx<AccessList = Self::AccessList>;
    type Eip4844: Eip4844Tx<AccessList = Self::AccessList>;
    type Eip7702: Eip7702Tx<AccessList = Self::AccessList>;

    /// Transaction type. Depending on this field other functions should be called.
    /// If transaction is Legacy, then `legacy()` should be called.
    fn tx_type(&self) -> Self::TransactionType;

    /// Legacy transaction.
    fn legacy(&self) -> &Self::Legacy {
        unimplemented!("legacy tx not supported")
    }

    /// EIP-2930 transaction.
    fn eip2930(&self) -> &Self::Eip2930 {
        unimplemented!("Eip2930 tx not supported")
    }

    /// EIP-1559 transaction.
    fn eip1559(&self) -> &Self::Eip1559 {
        unimplemented!("Eip1559 tx not supported")
    }

    /// EIP-4844 transaction.
    fn eip4844(&self) -> &Self::Eip4844 {
        unimplemented!("Eip4844 tx not supported")
    }

    /// EIP-7702 transaction.
    fn eip7702(&self) -> &Self::Eip7702 {
        unimplemented!("Eip7702 tx not supported")
    }

    ...
}

• This trait is implemented on previous TxEnv struct, and only field that was added was tx_type.
• Validation of transaction field is moved from Env to validation functions.
• AccessList and AuthorizationList are modelled as associated types traits. In follow up PR eip-* types will be moved inside the project when the default context gets extracted.
• Optimism crate is a good example to see how a new transaction type is added TxDeposit.
