Replay both key down and up for Win in GrabAndMove

[foxmsft]

Summary of the Pull Request

The code for keyup on the Win key would replay the previously absorbed keydown event and just leave this keyup to propagate normally, thus leading to a race condition between CallNextHookEx and SendInput. This resulted in almost guaranteed out-of-order event (Win up, followed by Win down) in the case of Win+G (the Xbox Game bar shortcut).

Fixed by also absorbing the keyup for Win, but calling SendInput for both keydown and keyup.
