Add state override functionality to superchain-ops 2.0

[blmalone]

For feature parity with the old superchain-ops system, tasks need a way to be able to override state. This is commonly used by task developers to override the nonce of the parent multisig (see here).

However, task developers should be able to define any state overrides, not limited to nonces. The base contracts Simulation.sol library has helper functions to assist with this.

Requirements for OPCM

• Override nonces
• Override thresholds
• Override implementation addresses on superchain level proxies e.g. this line will revert if we're doing a simulation where we are upgrading Base before OP has updated (Base doesn't use upgradeController address). OPCM enforces ordering in that OP mainnet/sepolia has to execute upgrade first before any other chain.
