LibretroAdmin 56b7172dee input: the SDL3 driver publishes its mouse, fingers and pen ...

SDL3 hands the frontend the mouse's frame, the fingers that are down
and the pen once a poll, and its own answers for the mouse, the pointer
and the lightgun's aim are deleted. Fingers are read before the pen and
the pen before the mouse, as before.

What the store learned for it:
- how many pointers are down (RETRO_DEVICE_ID_POINTER_COUNT): the
  touches that are, else the mouse standing for one. SDL3 answered
  this; the drivers converted before it gave 0, and now give the
  count too;
- a pointer placed as the lightgun is, -0x8000 outside the viewport,
  where the other drivers hold it to the edge
  (INPUT_POINTERS_POINTER_OFFSCREEN);
- a touch read alone (INPUT_POINTERS_TOUCH_ALONE): a pen in the air is
  a pointer that is not pressed, whatever the mouse's buttons say.
A touch is placed either way once a poll, as a mouse is.

pointer_frame_test covers the count and both flags.
