[hardhat-foundry] Add support for configuring path to foundry.toml

[NIC619]

Describe the feature

We install our Foundry repo as submodule and use hardhat to deploy and run scripts (because we are still more used to hardhat scripts) but since it is installed as a submodule the foundry.toml file is not in the root folder. We have to copy the foundry.toml to root directory and modify src path in the copied foundry.toml so hardhat-foundry can read from it and compile. It would be helpful to be able to configure path of foundry folder in hardhat config so hardhat-foundry can fetch the foundry.toml file in the foundry folder and compile.

Makes sense!

We should probably add a config path llike:

paths: {
  // other paths
  foundry: "foundry/foundry.toml"
}

And then pass the config path to the Foundry commands we run.

I'm not sure if this will be enough, though, because maybe we also need to change the cwd or do something else. This will need some research.

Thanks for taking a look at it!
