mac_newworld: implement custom FWPathProvider

Browse source 
This enables the correct generation of bootdevice fw paths for in-built IDE
and virtio-pci-blk devices suitable for OpenBIOS.

Note we also set the MachineClass ignore_boot_device_suffixes property to true
since an additional disk node should not be added except for virtio devices.
