[remote-playback] Change connect() to return Promise<void>

avayvod has just created a new issue for 
https://github.com/w3c/remote-playback:

== Change connect() to return Promise<void> ==
... and reject when user cancels the selection.
Having to wait for the Promise to be resolved and then to check if its
 value is true seems to make the examples less straightforward:

```javascript
videoElem.remote.connect().then(switchToRemoteUI);
```

vs.

```javascript
videoElem.remote.connect().then(function(success) {  if (success) 
switchToRemoteUI(); });
```
