Implement profiles (development, production)

[ilg-ul]

Implement multiple profiles to store separate development vs production definitions.

The configuration looks like this:

{
  "xpack": {
    "profiles": {
      "production": {
        "devDependencies": {
          "@micro-os-plus/build-helper": {
            "specifier": "@micro-os-plus/build-helper-xpack@1.2.3",
            "local": "link",
            "platforms": "all"
          }
        }
      },
      "development": {
        "devDependencies": {
          "@micro-os-plus/build-helper": {
            "specifier": "github:micro-os-plus/build-helper-xpack#xpack-develop",
            "local": "link",
            "platforms": "all",
            "force": true
          }
        }
      }
    }
  }
}

The command line is extended with --profile <name>.
