Solve the address discoverability by adding getters
on the system config for the L1 proxies. This is
very easy to accomplish, now the user only needs
to know the address of the systemconfig with
a particular op stack chain to know all of the
L1 contract addresses. It makes tracking all
of the chains in the superchain much easier.

There are still some todos for this PR,
a getter needs to be added for each address.

op-chain-ops: Fix flaky TestCode

If getting an empty code value in the state DB, geth returns `nil`,
not an empty array. This is funcationally equivalent if you are checking
the length, but not the same if you expect to get the same object out
that you put in. This now checks for this special case & prevents
the test from flaking.

This can be tested by running `go test ./state -count=10 -run=TestCode` in
the op-chain-ops folder. Without this change the test will fail, with this
change it will now pass.
