QCococaWindow: Add NSView hosting support.

Browse Source 
Add and export QCCoocaView::setContentView(NSView *),
making it possible to host a foreign NSView in a QWindow.

Change QCoocaWindow::m_contentView to be a generic
NSView, instead of a QNSView. Add a separate m_qtView
for code paths that expect a QNSView.
