Multi-chain support

[glitch-txs]

I wanted to ask Wagmi team if they are open to discuss a more chain agnostic protocol integration, this would mainly help multi-chain wallets to have a smoother UX when interacting with multi-chain Dapps, like connecting multiple chains at the same time, not injecting a provider for each chain, etc. The idea wouldn't be to replace EIP-1193 but rather adding support for a new CAIP, could also we an extension library for Wagmi/Viem inside the Wevm organization.
