vmm, main: make PCI BDF configurable for ConsoleConfig

Browse Source 
Add common PCI device configuration to the virtio-console device
configuration. This allows setting the device ID (the name), ID, the
PCI segment, and the PCI device ID (BDF), which were previously not
configurable for the virtio-console device.

This gives management software, such as libvirt, more control over PCI
resource assignment and aligns virtio-console with other devices that
already support this functionality [0].
