Provide webrender_api::RenderApiSender to ScriptThread and DOM Window
This will allow the HTMLMediaElement later to get a handle to the RenderApi for rendering video frames. At a later time, all media handling should be moved to its own thread/process that is communicated with via IPC. At that point this can be removed again.
