Add / test an account creation workflow

[NiloCK]

4337 Account creation flow looks like this:

• create a UserOp with
  • sender == your precomputed wallet address
  • initCode == contractFactoryAddress+encodedConstructorParameters

The entrypoint will call the given contractFactoryAddress with the given encodedConstructorParameters.

The wallet address can be precomputed with:

const accountAddress = ethers.utils.getCreate2Address(
  contractFactoryAddress,
  salt,
  scBridgeWalletContractBytecodeHash
);

To do:

• make a factory contract (add a factory for BridgeAccounts #16)
• add a deployed 4337 entrypoint contract to our hardhat / test config
• test precomputed addresses by hitting the entrypoint with an initAccount operation

@NiloCK are we having an entrypoint after all, then?

Yes. Entry point, but no bundler.
