[core] Propagate clock and logger from system

[davidkpiano]

The clock and logger specified in the options object of createActor(logic, options) will now propagate to all actors created within the same actor system.

import { setup, log, createActor } from 'xstate';

const childMachine = setup({
  // ...
}).createMachine({
  // ...
  // Uses custom logger from root actor
  entry: log('something')
});

const parentMachine = setup({
  // ...
}).createMachine({
  // ...
  invoke: {
    src: childMachine
  }
});

const actor = createActor(parentMachine, {
  logger: (...args) => {
    // custom logger for args
  }
});

actor.start();
