[Feature] Add ability to decorate sol! macro with style attributes (snake_case, serde rename)

[zerosnacks]

Component

contract

Describe the feature you would like

Follow up from: alloy-rs/examples#8 (comment)

Request is to add the ability to decorate sol! macro with style attributes.

Consider the following:

let IERC20::totalSupplyReturn { _0 } = contract.totalSupply().call().await?;

This would, when having been decorated by a snake_case attribute be transformed in:

let IERC20::total_supply_return { _0 } = contract.total_supply().call().await?;

Additional context

Any changes will be reflected in alloy/examples
