contracts-bedrock: modularize deployer script (#9061)

* contracts-bedrock: modularize deployer script

Move logic for interacting with artifacts outside
of the deployer contract into its own contract.

This allows for other contracts to easily inherit the
contract so that any contract can read in contract
addresses.

* ctb: handle devnet

* contracts-bedrock: fixup

* lint: fix
