Haixu Cui 6ab7b84fc2 virtio-spi: Add vhost-user-spi device support

This patch introduces support for vhost-user-spi and vhost-user-spi-pci
devices in QEMU, enabling virtio-based SPI communication via the vhost-user
protocol.

The implementation follows the virtio-spi specification and leverages
the upstream virtio-spi driver in Linux. Relevant references:

- Virtio SPI specification:
  https://github.com/oasis-tcs/virtio-spec/tree/master/device-types/spi
- Linux virtio-spi driver:
  https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/spi/spi-virtio.c?h=v6.18-rc3
- vhost-user-spi daemon:
  https://github.com/rust-vmm/vhost-device/tree/main/vhost-device-spi

Example usage with rust-vmm vhost-user-spi daemon:

Start the vhost-user-spi daemon:
    vhost-device-spi --socket-path=vspi.sock --socket-count=1 \
        --device "/dev/spidev0.0"

Launch QEMU with:
    qemu-system-aarch64 -m 1G \
        -chardev socket,path=/home/root/vspi.sock0,id=vspi \
        -device vhost-user-spi-device,chardev=vspi,id=spi \
        -object memory-backend-file,id=mem,size=1G,mem-path=/dev/shm,share=on \
        -numa node,memdev=mem
