Re: [webrtc-pc] Validation of reordered readonly parameters in setParameters

The order of the encodings is equivalent to their precedence, which is negotiated in SDP via "a=simulcast". So it doesn't make sense to try to reorder them, because it would require renegotiation, which none of the other things you can change in `setParameters` require.

We _could_ say "the order in 'a=simulcast' isn't absolute, it's a 'proposed preference', so the sender can choose to override it." Similar to what we did for codecs. But this would still be getting into "new feature" territory, so unless there's a good use case I'd suggest just not allowing this.
