This PR introduces a setup contract that can be called from the `Safe`
setup function in order to automatically promote a Safe at setup time if
the code is executing on an L2. Namely, this allows the Safe Proxy
factory to use a single singleton and initializer for all chains, but
end up with different `singleton`s depending on the chain ID.
The expected use of this contract is to use the standard proxy factory:
```solidity
Safe l1Singleton;
SafeL2 l2Singleton;
SafeToL2Setup l2Setup;
proxyFactory.createProxyWithNonce(
address(l1Singleton),
abi.encodeCall(
l1Singleton.setup,
(
owners,
threshold,
address(l2Setup),
abi.encodeCall(l2Setup.setupToL2, address(l2Singleton)),
fallbackHandler,
paymentToken,
payment,
paymentReceiver
)
),
saltNonce
)
```
On L1 (i.e. Ethereum Mainnet where `chainId == 1`), you would end up
with a Safe where `safe.singleton == l1Singleton` and on any other
chains, you would end up with `safe.singleton == l2Singleton`. This
would happen _before_ the first transaction.
