Bernhard Schelling c039576441
Fix quick shift key presses getting ignored on dinput driver (#17185) 
Because shift keys were ignored in the event message  and only issued during polling, a quick key press and release between polling would get ignored.
This change also fixes left alt up key events getting issued (and sent to the core) twice.
