Introduce eth_getAccountInfo

[mattsse]

Describe the feature

for evm fork testing we currently need to send 3 requests: balance,code,nonce

https://github.com/foundry-rs/foundry-fork-db/blob/5b03d6e9320d502daa3a6687298e59a51967de3e/src/backend.rs#L286-L289

It would be more useful to have this info in a dedicated endpoint.

there is eth_getAccount, but this returns the trie account, with codehash and storageroot which is not quite what we need for fork testing.

we basically need this info type as an rpc response

pub struct AccountInfo {
    /// Account balance
    pub balance: U256,
    /// Account nonce
    pub nonce: u64,
    /// Account code
    pub code: Bytes,
}

TODO

• we can first prototype this type in alloy-rpc-eth, replacing this type https://github.com/alloy-rs/alloy/blob/79e47906f8df58f2d0f69516374ea841c485bc39/crates/rpc-types-eth/src/account.rs#L9-L15
• then we can add provider function like https://github.com/alloy-rs/alloy/blob/79e47906f8df58f2d0f69516374ea841c485bc39/crates/provider/src/provider/trait.rs#L351-L355

Once we have that, we can add this to reth by

1. adding support for this like

   reth/crates/rpc/rpc-eth-api/src/core.rs

   Lines 702 to 710 in 61a0345

   	/// Handler for: `eth_getAccount`
   	async fn get_account(
   	&self,
   	address: Address,
   	block: BlockId,
   	) -> RpcResult<Option<alloy_rpc_types_eth::Account>> {
   	trace!(target: "rpc::eth", "Serving eth_getAccount");
   	Ok(EthState::get_account(self, address, block).await?)
   	}
