[Feature] typed hardforks for anvil bindings

[siosw]

Component

node-bindings

Describe the feature you would like

currently starting an anvil node with a hardfork enabled looks like this:

let provider = ProviderBuilder::new()
    .with_recommended_fillers()
    .on_anvil_with_wallet_and_config(|anvil| anvil.arg("--hardfork").arg("prague"));

anvil itself represents this as hardfork::Option<ChainHardfork>
i think it would be neat if we could do:

let provider = ProviderBuilder::new()
    .with_recommended_fillers()
    .on_anvil_with_wallet_and_config(|anvil| anvil.hardfork(EthereumHardfork::Prague));

happy to pick this up if there is consensus around implementing this

Hey @mattsse, is it possible to work on this issue without disrupting reth?

[mattsse]

I think we really just need a new repository for this, created https://github.com/alloy-rs/hardforks

feel free to submit a pr that adds the reth crate + extras.
the reth-ethereum-forks doesn't have any reth deps so we can extract this in one go

The reth-ethereum-forks crate contains some workspace dependencies. If it’s not a problem for you, I’d like you to submit only the initial setup. In Cargo.toml, it uses dependencies based on the workspace.

[mattsse]

those workspace deps need to be converted when it is extracted

Sure
Currently, I can’t send anything to the repository because creating a fork is not allowed

[mattsse]

initialized it

i have a PR for this once hardforks crate is in
