Add more overloads using GlobalFrameRoutingId

This CL adds an overload to WebContentsImpl::FromRenderFrameHostID()
and to RenderFrameHost::FromID() that takes in a GlobalFrameRoutingId
instead of taking in a pair of ints.

This makes those functions easier to use when the caller already has
a GlobalFrameRoutingId instance.
