[TASK] Write a cross-chain test where all similar contracts have the same address

[drewstone]

Leverage existing cross-chain tests where possible, but overall we want to define a process where we ensure the contract deployments are consistently the same with Create2 deployments. Specifically ensure that

• [ ] Signature bridge contracts are the same address on different chains
• [ ] GovernedTokens are the same address on different chains
• [ ] Any other contracts involved

Chainalysis oracle is deployed to many chains with the same address and this is quite nice.
