video: Don't switch display modes when emulating mode changes

Browse Source 
SDL uses window minimization to determine fullscreen window visibility and hide windows before changing the video mode back to the desktop. Wayland, however, does not have the concept of a minimized window and doesn't set the minimized flag (minimization can be requested, but what actually happens to the window is implementation dependent, and if a window is minimized via a desktop shortcut or decoration control, the application is not notified of any state changes). Make the video core mode setting a no-op so that the Wayland backend can handle reporting the display dimensions using its own internal logic.
