cc: Pipe visibility and memory allocation to DelegatingRenderer

The GPU process makes memory allocation decisions based on the visibility of
surface. In the DelegatingRenderer case we don't use the surface directly, but
we still have it - just like composite-to-mailbox. So we can use
setVisibilityCHROMIUM to signal the GPU process, and listen to the memory
allocation callback.

This CL refactors a bunch of the logic that was hardcoded in GLRenderer into
OutputSurface which is shared. That also opens the door to implementing a memory
manager for the software renderer.
