[Redux DevTools] Add support `Sync` feature between the windows

It's similar to the `Sync` trigger in `remote-redux-devtools` monitor:

It will sync actions / state between all instances, but if we want to do this in here, we may sync the `debugger windows` instead of `instances`, and depends the store `name` for sync it.

This would be useful when debugging both iOS and Android or multiple real devices.

## In progress

- [x] Added sync device actions, support #119
- [ ] Support `STATE` devtools action
- [ ] Support multiple store by match `name`

See [the comment](https://github.com/jhen0409/react-native-debugger/pull/119#issuecomment-321735565).

Start by reviewing the sync device actions added in pull request #119 and the linked issue comment. Complete support for the STATE devtools action and for matching multiple stores by name, then verify that actions and state synchronize between debugger windows for the intended devices and stores.
