Allow to indicate that a task is required in all packages

Goals

1. Prevent a package from accidentally NOT running a task

Non-goals

No response

Background

I would like to be able to make some tasks mandatory. I have already forgotten to implement a task in a package.

Proposal

{
  "tasks": {
    "typecheck": {
      "required": true
    }
  }
}

If a package does not have the typecheck script, turbo would throw an error when trying to run that task
