Implement an OperationsChain, to be used by PeerConnection in follow-up.

This allows asynchronous tasks to be queued to be executed in order.
The class is motivated by the "operations chain" in the spec:
https://w3c.github.io/webrtc-pc/#dfn-operations-chain

In a follow-up CL I intend to use this in PeerConnection's
CreateOffer(), CreateAnswer() SetLocalDescription() and
SetRemoteDescription() and unblock https://crbug.com/980885.

For background, motivation, requirements and implementation notes, see
