  wayland: Avoid a pointer→TouchID cast warning
  
  As of [1], SDL now compiles with a warning in SDL_waylandevents.c on
  32-bit systems under gcc 10.3.0:
  
  /tmp/SDL/src/video/wayland/SDL_waylandevents.c: In function 'seat_handle_capabilities':
  /tmp/SDL/src/video/wayland/SDL_waylandevents.c:958:22: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
    958 |         SDL_AddTouch((SDL_TouchID)seat, SDL_TOUCH_DEVICE_DIRECT, "wayland_touch");
        |                      ^
  /tmp/SDL/src/video/wayland/SDL_waylandevents.c:964:22: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
    964 |         SDL_DelTouch((SDL_TouchID)seat);
        |                      ^
  
  This is due to SDL_TouchID always being 32-bit, but seat being a pointer
  which is (obviously) only 32-bit on 32-bit systems. The conversion is
  therefore harmless, so silence it with an extra cast via intptr_t.
  
  This is what the cocoa backend does (and is similar to what the Win32
  backend does, except with size_t).
  
  Fixes: 03c19efbd1 ("Added support for multiple seats with touch input on Wayland")
