Implement dom exception constructor

I have a question: should I edit `./mach test-wpt` expectations?

Update StyleSheet.insertRule WebIDL to make index optional.
Update wpt metadata to show the new passes.
Add one test as crashing since currently passing an \@import rule to insertRule
leads to "Expected a stylesheet loader for \@import"

Add optional annotations for initEvent method of Event interface
Added `optional` and default values to parameters `bubbles` and `cancelable` of `initEvent` of `Event`.
I tried to update test results, but there seem to be no differences at all.
I checked similar code where `optional` is used, and there seems to be no special handling in Rust. If that is not the case with this issue, please let me know and I'll commit more follow-ups.

Initial webrtc and getUserMedia DOM support
This is able to reach the point where connections are properly negotiated and ready to exchange streams.
<s>The `toJSON()` stuff doesn't work yet, so most example code will need to be tweaked to manually construct JSON first before sending SDP and ICE messages over websockets. I'll add support for this soon. (This may need webidl tweaks to support `[Default]` and `toJSON()`)</s>
For some reason I haven't yet figured out, connections are one-way, Servo is able to receive streams but the other end doesn't see the streams Servo sends. I don't think this is due to https://github.com/servo/media/issues/191, but that bug is making it harder to test.
This implementation simply drops streams that it receives, without connecting them up to any output elements, since servo-media-player doesn't yet have mediastream support.
Since servo can neither effectively send nor receive streams this implementation isn't useful yet, however it is getting large and I figured I'd get it reviewed and landed early as a base.
