Closure cheatcode for interacting with contract_state_for_testing

[cptartur]

Current State

Currently, contract_state_for_testing doesn't play nicely with normal flow of tests - changes to the storage made through it aren't reflected in the standard test execution (using dispatchers).

The state not being reflected is caused by ContractState returned by contract_state_for_testing using different storage addresses than the contract used by dispatcher (details to be researched, supposedly it assumes the contract address to be 0).

By cheating the contract address, we can make the ContractState work with the normal fow

Objective

Implement the closure cheatcode for interacting with contract_state_for_testing

Additional Context

Example interface should be something along the lines of this

fn modify_state<
    F, 
    +Drop<F>,
    impl func: core::ops::Fn<F, ()>,
>(contract_address: ContractAddress, f: F) -> func::Output {
    // start cheat
    f()
    // end cheat
}
