* @description 格式化tree属性为TreeSelect所需
* @function formatTreeSelectProps
* @param {object} obj - 入参对象
* @param {object} obj.tree - 原始tree
* @param {object} [obj.fieldNames={id: 'key', label: 'label', children: 'children'}] - 格式化tree所需的属性
* @param {boolean} [obj.parentSelectable = false] - 父级是否可选择，默认不可选
* @returns {array} 格式化后符合TreeSelect的tree
