do we need this on WebContents? Why not just add to the public RenderViewHost
base class?

tactically, as it's only needed on Android, it maybe simpler to add this to
ContentViewCore .java / .cc, as content_view_core_impl.cc can see other content
internal APIs and so could poke straight into
GeolocationDispatcherHost::PauseOrResume() etc. No need for cross-plat public
API?

i thought about this at first, but it seemed more a WebContents-y API than RVH.
But I really don't feel strongly either way.
SGTM. no need for CVC.java though, is there? Can go straight to native from
AwContents native?
