[Feature] Add json path as const field of `sol!` generated mod

[alexfertel]

Component

sol! macro

Describe the feature you would like

Say we have the following macro invocation:

alloy::sol!(
    #[sol(abi)]
    UniswapV2Reader,
    "src/abis/UniswapV2Reader.json"
);

There is no way to recover "src/abis/UniswapV2Reader.json" from UniswapV2Reader. It would be nice to be able to access the path to the json file that generated a given module.
