hw/display/apple-gfx: Adds configurable mode list

Browse source 
This change adds a property 'display_modes' on the graphics device
which permits specifying a list of display modes. (screen resolution
and refresh rate)

The property is an array of a custom type to make the syntax slightly
less awkward to use, for example:

-device '{"driver":"apple-gfx-pci", "display-modes":["1920x1080@60", "3840x2160@60"]}'
