* contracts-bedrock: flake fix attempt

Progress towards fixing flakes in CI. Using `etch` to set contracts in
state instead of deploying will help to fix the nonce mismatches between
the L1 contract addresses and the L2 genesis that contains L1 contract
addresses.

Developers will need to run `forge clean` to remove artifacts for the
tests to pass after this commit is merged. It enforces a single version
of `FFIInterface` to be compiled instead of it being compiled with
multiple compiler versions. The `vm.getCode` family of cheats fail when
there are multiple compiled versions of the same contract because the
artfact has the compiler version appended to the name of the artifact.

This will also help to improve compiler time since the compiled
contracts do not need to include the compiled bytecode of the deploy and
ffiinterface contracts, the code is loaded dynamically instead of being
deployed with `CREATE`.

* contracts-bedrock: more cleanup

Deletes a dead file that is no longer needed and sets the deploy config
in state using `etch`. `DeployL2` is not used, we should be using the
`superchain-ops` repo for deploying new L2 contracts or deploy them
through L1. Since `DeployL2` used code using solc `0.8.19` (EAS) it
caused multiple versions of the `DeployConfig` to be compiled which
causes headaches when using `vm.getCode`.
