Qt: Fix Exclusive Fullscreen not on right display

Add an explicit create() call that creates the HWND early . This makes sure when when rendering to main window, it stays on the current display the main window is at. This fixes the bug where rendering to main with exclusive fullscreen would move to the primary monitor.

Not everyone may need this fix. Create() is implicity called in showFullscreen() or showNormal(), but there might be some certain combination of Windows settings or devices that may need it.
