Add stubs for HTMLCanvasElement.captureStream and WebRTC transceiver APIs
These stubs are hidden by default and only exist to allow getting past the relevant code that invokes them on hubs.mozilla.org.
Specifically, I changed the `text` field of `ScriptOrigin` from a
`DOMString` to an `Rc<DOMString>`. Then I updated all the related code
to work with an `Rc`.
This is just a first pass to get the code to compile. There are probably
more things I can do that will improve the code and further reduce
cloning.
Implemented HTMLFormElement.relList
<!-- Please describe your changes on the following line: -->
Updated the tests to reflect addition of rel and relList for HTMLFormElement, as well as porting those code snippets from HTMLAnchorElement.
