[webrtc-pc] support for alpha channel when transferring canvas. (#2920)

jimmywarting has just created a new issue for https://github.com/w3c/webrtc-pc:

== support for alpha channel when transferring canvas. ==
`RTCPeerConnection` does not seem to support the alpha channel. 
is there any trick into choosing a encoder / codec that supports alpha channel also?

the video i'm capturing is coming from a `canvas.captureStream()` and it dose not have a background.
and the receiver instead sees a solid black background.

it's evident on demos such as:
- https://webrtc.github.io/samples/src/content/capture/canvas-pc/
- https://stackoverflow.com/a/58341171/1008999
