Fix windows created with SDL_WINDOW_MINIMIZED having inconsistent SDL_WINDOW_HIDDEN flag on Windows

Browse Source 
- Windows created minimized are shown with SW_SHOWMINNOACTIVE which does not send WM_SHOWWINDOW leaving the window visible (but minimized)
  on desktop but still with the SDL_WINDOW_HIDDEN flag set. Now the hidden flag is cleared in this case but noted that this means it's not currently possible
  to create a window that is initially hidden that then is minimized once shown.
