op-viem & op-wagmi --> optimism viem/wagmi

[fainashalts]

Based on the meeting notes here, we need to make some updates to our viem and wagmi packages to ensure needed functionality remains available to developers.

Bindings for L1/L2 Pathways

• OptimismPortal Bindings #616
• CrossDomainMessenger Bindings #617
• StandardBridge Bindings #618

Superchain Registry

• automatic viem chain definitions for all members in the registry #614

Misc

• Remove all references to op-viem
• Remove all references to the SDK (complete deprecation)
• Ecosystem package documentation

Once these tasks are complete, we should also evaluate any places (if any) we're using op-viem internally so we can switch to our own implementation. There appear to be a couple of places we may want to check on.
