Cocoa: Make sure we update internal window fullscreen state

We update the internal/synched state by assigning it its QWindow's
state. Since that one is not a flag, it can only be in one state at
a time, meaning that we may lose the maximized state (but we've been
losing it for some time).

Cocoa: Make QWidget::showNormal() work on minimized windows

Cocoa sets the NSWindow hidden when it's minimized, and we don't
propagate that further to QWindow or QWidget (QWidget's 'visible'
documentation is quite ambiguous about that state).

The obvious fix is to check for QWindow's visibility. However, this
might need to be corrected later if we truly want the visible state
to be in sync.
