Add deploy flag to Fuels CLI build command

[arboleya]

Before being able to build frontend applications, users must run fuels build to generate all required files.

However, the contract-ids.json file is only created when contracts are deployed via the deploy command.

That's why we need this flag, to make it straightforward to have routines like:

{
  "scripts": {
    "prebuild": "fuels build --depoy",
    "build": "next build",
  }
}

This was a requirement for #1408
