  video: Add SDL_SetWindowMouseRect.
  
  This API and implementation comes from the Unreal Engine branch of SDL, which
  originally called this "SDL_ConfineCursor".
  
  Some minor cleanup and changes for consistency with the rest of SDL_video, but
  there are two major changes:
  
  1. The coordinate system has been changed so that `rect` is _window_ relative
     and not _screen_ relative, making it easier to implement without having
     global access to the display.
  2. The UE version unset all rects when passing `NULL` as a parameter for
     `window`, this has been removed as it was an unused feature anyhow.
  
  Currently this is only implemented for X, but can be supported on Wayland and
  Windows at minimum too.
