* contracts-bedrock: cleanup predeploys solidity test

Contributors to the smart contracts have way too many steps
to get their PR over the line. This migrates some of the `check-l2`
script to solidity. I believe that we can fully delete `check-l2`
but want to follow up in an additional PR to ensure that we have the
same functionality. Completely deleting `check-l2` was unblocked by
https://github.com/ethereum-optimism/optimism/pull/8911.

The functionality that is added to the solidity here was removed from
the `check-l2` script.
