chore: replace anvil hardforks with alloy-hardforks

[mattsse]

Component

Anvil

Describe the feature you would like

we effectively have this duplicated now

foundry/crates/anvil/src/hardfork.rs

Lines 8 to 12 in d20a9b3

	#[derive(Clone, Copy, Debug, PartialEq, Eq, PartialOrd, Ord, Hash)]
	pub enum ChainHardfork {
	Ethereum(EthereumHardfork),
	Optimism(OptimismHardfork),
	}

and ideally we can replace this entirely with alloy-hardforks

Additional context

No response

May I look into this ? :)
