macOS: Make sure NSResizableWindowMask is set when toggling fullscreen

Browse Source 
Instead of setting the mask in toggleFullScreen(), which is only hit
when going to fullscreen via our own API, we do it in the window
notification callbacks, which also includes going to full screen via
the native macOS title bar buttons. This allows making customized
windows without Qt::WindowMaximizeButtonHint full screen with the
full geometry of the screen.
