fix(treeTable): 修复重载数据时，指定参数 scrollPos: 'fixed' 无效的问题 (#1892)

* 修正treeTable重载数据时，指定参数 scrollPos: 'fixed' ，无法实现保持滚动条在原有位置的问题。 * 1，把修改代码移动到Class.prototype.render方法体中； 2，把let修改为var * 修改let->var * Update src/modules/treeTable.js Co-authored-by: morning-star <26325820+Sight-wcg@users.noreply.github.com> * Update src/modules/treeTable.js Co-authored-by: morning-star <26325820+Sight-wcg@users.noreply.github.com> * 按照评审人给出的修改意见进行修改主要修改点： 1，通过给done包装函数设置scrollPosPatch标志位，避免重复包装； 2，包装后的done函数执行完毕后，恢复原来的done函数，避免以后再次触发done函数时，仍然执行保持滚动条位置的逻辑； * 函数调用时，call->apply * refactor: 简化代码 1. 将修复代码迁移至 updateOptions 2. table done 回调第四个参数，现在可以区分 reloadData 和 renderData --------- Co-authored-by: morning-star <26325820+Sight-wcg@users.noreply.github.com>
