Currently, virtio transports for each device are determined with architecture dependent build time conditionals. This isn't the ideal solution, as virtio transports aren't exactly tied to the host's architecture. For example, aarch64 VMs do support both PCI and MMIO devices, and after the recent introduction of the microvm machine type, that's also the case for x86_64. This patch extends each device that supports multiple transports with a VirtioTransport field, so users of the library can manually specify a transport for each device. To avoid breaking the compatibility, if VirtioTransport is empty a behavior equivalent to the legacy one is achieved by checking runtime.GOARCH and Config.Machine.Type. Keeping support for isVirtioPCI/isVirtioCCW in qmp.go is a bit tricky. Eventually, the hot-plug API should be extended so callers must manually specify the transport for the device.
