Required input for spawn when defined inside referenced actor

[SandroMaglione]

Similar to #5055, this PR makes input required when using spawn and the input type in the referenced actor is defined.

This prevents issues when forgetting to pass an input when using spawn (causing runtime errors).

const childMachine = createMachine({
  types: { input: {} as { value: number } }
});

const machine = createMachine({
  types: {} as { context: { ref: ActorRefFrom<typeof childMachine> } },
  context: ({ spawn }) => ({
    ref: spawn(
      childMachine,
      // Input is now required!
      { input: { value: 42 } }
    )
  })
});

The return type errors without this bypass. I think this is expected given that typescript has not enough information to correctly type-check all possible configurations.

All tests are passing, so I think it shouldn’t be an issue (the update is mostly on the types).

we don't really check that it's required here, u just pass an input as an argument but the same test would pass without the patch introduced by this PR

[SandroMaglione]

Should this be inverted with a @ts-expect-error instead? Or is there another better way to test types?
