Cocoa: Make sure we can display multiple sheets for the same NSWindow
On macOS, to display a modal with Qt::WindowModality set, or of type
Qt::Sheet, we call beginSheet:completinHandler:. However, this method
won't display the specified sheet unless the current active one is
dismissed, which is a different behavior than what we expect for
this case. Use beginCriticalSheet:completionHandler: whenever we
already have an active sheet attached to the NSWindow, which allows
us to display multiple sheets for the same window.
