Expose the mouse focus functions from Wayland::Compositor

For Compositors to handle mouse focus handling, ie enter/leave. This
calls down into wayland-server which keeps track of which surface holds
the focus. Trivial implementation in compositor would be to call
this function for all mouseMove events. I believe overhead should not be
significant.
