[OffscreenCanvas] Add API for driving animation callbacks with OffscreenCanvas

Project Member Reported by junov@chromium.org, Dec 20 2016 
The exact form for this API has not been nailed down yet. Could be something like requestAnimationFrame, or commit() could return a promise that resolves when it is time to render the next frame.

Spec discussion is here:

Implementing promise-based commit for driving OffscreenCanvas animations

This is an experimental prototype API for demonstrating a proposal to use
promises instead of requestAnimationFrame for driving animations.  This
initial implementation uses a delayed task to simulate the BeginFrame
signal.  Properly hooking-up BeginFrame will be solved in a follow-up
code change.

This API was discussed here:
