Fix GraphicsBuffer tracking in InternalWindow
If markAsMapped() is called, the window may be resized, for example due
to window placement. If that happens, the QWindow may repaint itself
immediately and potentially drop the swapchain; it all will occur
recursively in markAsMapped(). If there is a nested present(), i.e.
present() -> markAsMapped() -> present(), the graphics buffer reference
in the outer present() can be invalid
markAsMapped();
m_graphicsBufferREf = frame.buffer; // frame.buffer can be deleted now
In order to prevent accessing destroyed graphics buffers, this change
makes the mark as mapped step last. As a long term measure, we need to
reconsider how geometry updates flow.
