Description of the issue

During multiplayer game with 2 or more controllers connected, when the controller for Player 2, 3 or 4 disconnects, Controller 1 assumes control ONLY when any action buttons (A/B/X/Y) are pressed. It does not assume Control when other buttons are pressed.

Reproduction steps

Playing Kirby Star Allies. (Or other game with 2+ player support)

1. Connect 2+ Controllers.
2. Enter any level and join players 2+.
3. Turn off or Disconnect controller 2, 3, or 4.
4. Press A to allow CPU play when prompted for disconnected controller.
5. Press any action button (A/B/X/Y)
6. Player 1 is now in control of any of the players that disconnected.

src\Ryujinx.Input\HLE\NpadManager.cs

Before:

                    inputState.PlayerId = playerIndex;
                    motionState.Item1.PlayerId = playerIndex;

                    _hleInputStates.Add(inputState);
                    _hleMotionStates.Add(motionState.Item1);

After:

                    inputState.PlayerId = playerIndex;
                    motionState.Item1.PlayerId = playerIndex;

                    if (!_blockInputUpdates && controller != null)
                    {
                        _hleInputStates.Add(inputState);
                    }

                    _hleMotionStates.Add(motionState.Item1);
