Standardize guest Input format

[CeciliaZ030]

Describe the feature request

All guests should start building from the same input struct, currently we have Input which is responsible for block-building and TaikoSystemInfo which contains the current state of L1 & L2.

pub struct Input<E: TxEssence> {
    pub parent_header: Header,
    pub beneficiary: Address,
    pub gas_limit: U256,
    pub timestamp: U256,
    pub extra_data: Bytes,
    pub mix_hash: B256,
    pub transactions: Vec<Transaction<E>>,
    pub withdrawals: Vec<Withdrawal>,
    pub parent_state_trie: MptNode,
    pub parent_storage: HashMap<Address, StorageEntry>,
    pub contracts: Vec<Bytes>,
    pub ancestor_headers: Vec<Header>,
    pub base_fee_per_gas: U256,
}

pub struct TaikoSystemInfo {
    pub l1_hash: B256,
    pub l1_height: u64,
    pub l2_tx_list: Vec<u8>,
    pub prover: Address,
    pub graffiti: B256,
    pub l1_signal_root: B256,
    pub l2_signal_root: B256,
    pub l2_withdrawals: Vec<Withdrawal>,
    pub block_proposed: BlockProposed,
    pub l1_next_block: Block<EthersTransaction>,
    pub l2_block: Block<EthersTransaction>,
}

• Collapse them to one struct, make sys_info as a field or the other way around
• Change all guests instance to adapt to new input format
• Also fix Powdr Input Deserialization #37 on the way :)

@CeciliaZ030 Should the PR be against the multi-guest branch on your repo?
