Add OverwriteContractCode method to ArbDebug precompile

[KolbyML]

fixes NIT-3993

problem

For benchmarking purposes, we would like to write to storage slots of existing contracts without private keys for the contracts. To do that, we want to be able to replace any contract code with a simple permissive contract code. This custom contract code will implement method facilitating the arbitrary writes to the contract's storage.

solution

• Add a method to the ArbDebug procompile which overwrites the specified contracts code
• Add a test to make sure the new method works as expected

I also had to update ArbDebug's solidity interface in OffchainLabs/nitro-precompile-interfaces

• ArbDebug: add overwriteContractCode interface nitro-precompile-interfaces#20

^ so this should probably be reviewed first
