display: Handle entering NULL windows (desktop)

Browse Source 
On X meta_window_handle_enter was called when the desktop window was
entered. On wayland the "desktop" is no window anymore. We still want to
inform the core that the desktop is focused, so it can unfocus windows
if focus-mode is mouse.

This commit prepares the core for handling a NULL windows to mean the
desktop.
