Unified OutputSurface::SwapBuffers.

This patch introduces a hard contract that CC will always call
OutputSurface::SwapBuffers(), and OutputSurface will always respond with
OutputSurfaceClient::OnSwapBuffersComplete(), in all rendering modes.  I
deleted the methods SendFrameToParentCompositor, PostSubBuffer, and
OnSendFrameToParentCompositorAck, subsuming them into SwapBuffers. I also
deleted all the settings and capabilities specifying which variant needed to be
called. 

This should be a no-op for all graphics modes except for Android WebView, where
it has the benefits of ensuring OnSwapBuffersComplete is called and that
CompositorFrameMetadata is available even though no parent compositor exists.
