Allow machine inspection/event logs for actors created via setup or invoke, or spawn.

// expected API

/// imports ...

const { inspect } = createBrowserInspector()
const machine1 = setup({...}).createMachine({
  context: {...},
  on: {...},
  // !!! here
  inspect: inspect
})

const machine2 = setup({ actors: { machine1 }}).createMachine({
  context: {...},
  initial: 'init',
  states: {
    init: {
      invoke: [
        {
          id: 'machine1',
          src: 'machine1'
        }
      ]
    }
  }
})

Whenever machine2 is started (however) and machine1 is invoked (or spawned), the inspect fn automatically logs all the events, transitions and snapshots of machine1

It doesn't necessarily have to be an inspect function, just a way to log everything going on in a machine in a filterable way (and inspect already exists hence asking in that direction).
