Add optional domain tag attribution to write contract method

[iainnash]

Opensea and Gem use an attribution (4 byte domain tag) for calls made from their site to trace what site originated the request.

Right now, typescript-wise it's a bit awkward to extend WAGMI since some of the types are internal and it would be a great option to either add a domain tag to the calldata generation.

This could either be passing in the domain or allowing appending calldata on the prepare/write side.
