Reduce chain config addresses to minimal set

[bitwiseguy]

The chain config .toml files should not contain contract/role addresses that can be changed frequently, causing the config file to become stale. All addresses can be read from addresses.json codegen file, which is frequently updated for all chains instead of requiring chain operators to open prs to update individual addresses each time one changes.

The only addresses that must be kept in the config file:

• SystemConfigProxy
• L1StandardBridgeProxy
• OptimismPortalProxy
• ProxyAdminOwner
