【工单编排】前端组件新增多选下拉支持

[benero]

背景：只有只有【单选下拉】协议，需要在编排时支持按【多选下拉】显示，type 是 list

        {
            "key": "role_id",
            "name": "角色",
            "required": true,
            "type": "string",
            "options": [
                {
                    "text": "资深运维",
                    "value": "engineer"
                },
                {
                    "text": "运维开发",
                    "value": "developer"
                }
            ]
        }
