epic: refacto the Message struct

[ClementWalter]

Why

The current message differs from the reference EELS one.

    struct Message {
        bytecode: felt*,
        bytecode_len: felt,
        valid_jumpdests_start: DictAccess*,
        valid_jumpdests: DictAccess*,
        calldata: felt*,
        calldata_len: felt,
        value: Uint256*,
        caller: felt,
        parent: Parent*,
        address: felt,
        code_address: felt,
        read_only: felt,
        is_create: felt,
        depth: felt,
        env: Environment*,
        cairo_precompile_called: felt,
    }

@dataclass
class Message:
    """
    Items that are used by contract creation or message call.
    """

    caller: Address
    target: Union[Bytes0, Address]
    current_target: Address
    gas: Uint
    value: U256
    data: Bytes
    code_address: Optional[Address]
    code: Bytes
    depth: Uint
    should_transfer_value: bool
    is_static: bool
    accessed_addresses: Set[Address]
    accessed_storage_keys: Set[Tuple[Address, Bytes32]]
    parent_evm: Optional["Evm"]

1. Keeping the same structs with the same naming ease the dev
2. we miss the accessed addresses and storage_keys slots (we used the reference data from starknet in kakarot);
