BACKENDS: Also hide mouse cursor outside game area when an engine has hidden the cursor

The only reason we show the system cursor outside the game area is
to show users where their mouse is when the window is resized and
the mouse is outside the game area. If the game cannot be
interacted with, then the mouse also does not need to be shown in
the black areas.
