This patch adds ivshmem region ID configuration support when user configure ACRN IVSHMEM devices via ACRN config tool, this ID provides VMs with a stable identification of multiple shared memory regions. Also add logic to generate launch script with region ID configured as below: `add_virtual_device 8 ivshmem hv:/shm_region_0,256,1` Tracked-On: #8566 Signed-off-by: Kunhui-Li <kunhuix.li@intel.com> Signed-off-by: Yonghua Huang <yonghua.huang@intel.com> Reviewed-by: Junjie Mao <junjie.mao@intel.com>
