Pipe SwapBuffers call{,backs} through ContextSupport

This plumbs the SwapBuffers calls and callbacks through the
gpu::ContextSupport interface instead of WGC3D. There are two production
paths for the callbacks - using Echo and using View IPCs. The former is
used everywhere except for single-threaded mac and guest plugin mode.
This implements the Echo path directly in GLES2Implementation and leaves
the implementation of the non-Echo path in WGC3DCommandBufferImpl. We'll
still have to clean that up to avoid having to allocate a WGC3D, but this
at least gets rid of the API dependencies from cc.
