kvm虚拟机新增 #79 中new标签的特性支持。

【验证方法】
在qemu仿真器中进行验证。

1. 仿真器版本：
qemu版本：

[root@dev rvck]# /usr/bin/qemu-system-riscv64 --version
QEMU emulator version 10.0.0 (qemu-10.0.0-6)
Copyright (c) 2003-2025 Fabrice Bellard and the QEMU Project developers

仿真器中运行的内核版本为rvck合入此补丁集的版本：

[root@localhost rvck]# uname -a
Linux localhost.localdomain 6.6.101+ #2 SMP Tue Aug  5 07:18:33 EDT 2025 riscv64 riscv64 riscv64 GNU/Linux

2. qemu-kvm虚拟机版本
qemu版本：qemu-10.0.0
内核版本 ：rvck内核版本

3. qemu-kvm虚拟机启动命令

/usr/bin/qemu-system-riscv64 \
        -nographic -enable-kvm \
        -machine virt,pflash0=pflash0,pflash1=pflash1,acpi=on,aia=aplic-imsic,accel=kvm \
        -blockdev node-name=pflash0,driver=file,read-only=on,filename="./RISCV_VIRT_CODE.fd" \
        -blockdev node-name=pflash1,driver=file,filename="./riscv_test_VARS.fd" \
        -smp 4,sockets=2,dies=1,clusters=1,cores=2,threads=1 \
        -m 4G \
        -kernel /boot/vmlinuz-6.6.101+ \
        -initrd rootfs.cpio \
        -append "no_hash_pointers crashkernel=128M loglevel=8 no5lvl earlycon console=ttyS0 root=/dev/ram rdinit=sbin/init"
        -object rng-random,filename=/dev/urandom,id=rng0 \
        -device virtio-rng-device,rng=rng0 \
        -device virtio-net-pci,netdev=net1 \
        -netdev tap,id=net1,ifname=vnet1,script=no,downscript=no \
        -cpu host\
        -device qemu-xhci \
        -usb -device usb-kbd \
        -device usb-tablet \
        -chardev socket,id=qmp,path=/var/lib/libvirt/qemu/riscv-test,server=on,wait=off \
        -mon mode=control,chardev=qmp

4. 特性验证
虚拟机启动成功后，登陆虚拟机执行： cat /proc/cpuinfo

~ # uname -a
Linux (none) 6.6.101+ #2 SMP Tue Aug  5 07:18:33 EDT 2025 riscv64 GNU/Linux

该补丁系backport自上游社区，主要是规范实现，较少函数功能实现。

该pr进入物理机器验证阶段，通过后尝试合并。
