feat(protocol): allow DelegateOwner to delegatecall for batching

[dantaik]

If we want to use one L2 transaction to upgrade all contracts that are owned by DelegateOwner, then we need to allow DelegateOwner to delegatecall to a multicall3 contract.

Note that on L1, when we use Gnosis safe wallet, the wallet supports delegatecall too, so we can also batch-upgrade L1 contracts with one single transaction. A few unit tests have been added to verify batching is possible.

In this PR, I also added a dry-run fuction to verify calls on L2 will succeed. This function will come handy when we try to construct the calldata on L1.
