Re: [webrtc-pc] addTransceiver does not check for uniqueness of rid (#2733)

I've [tested](https://jsfiddle.net/jib1/sLfntv1e/) this and all browsers allow it. I agree it would be better if it threw.
```js
const transceiver = pc.addTransceiver("video", {sendEncodings: [{rid: "hi"}, {rid: "hi"}]});
```
For symmetry how is a remote offer with `a=simulcast:recv hi;hi` treated?
