The previous approach of traversing the machine and its device tree at startup to register CLI11 options was not working for dynamically registered devices like PCI cards. This meant that options like gfxmem_size or mon_id from the video cards could not be set. Switch to instead registering in MachineFactory a hook function that provides CLI flag values. We can call it when registering any property, whether at startup or dynamically.
