this makes Overlay accessible to renderer as well, right? do we need a separate
registrar just for gpu?

as far as i can tell, it does not make it available.  one must also add the
interface in remote interfaces in RenderProcessHostImpl, and update the service
manifest to allow connections from the renderer.

i'm still a little sketchy, but it seems like this makes it available in the
browser.  the other steps advertise it to the other processes.
