Add search field to memory tooling

We should add a search field here so that users can search for the class they are looking for. I wanted to look at the instances of a specific class and had to manually scroll through the list.

未指定文件或测试名称。首先定位内存工具界面和类实例列表，然后跟踪该列表的构建方式。当用户可以在搜索字段中输入类名，并查看匹配的类实例而无需手动滚动时，即视为完成；如果该界面已有测试覆盖，请添加或更新测试。
