Allow out-of-process iframes to render to compositing surfaces.
When compositing surfaces are enabled, the browser process upon
receiving a frame from an OOPIF will pass a surface identifier to the
embedding renderer process rather than the frame itself. This prevents
frames from having to be composited at an arbitrary number of levels
when OOPIFs are chained.
