Subject: [PATCH] perf: perf the control logic of Tab (#6220)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* perf: perf the control logic of Tab

* 每个标签页Tab使用唯一的key来控制关闭打开等逻辑
* 统一函数获取tab的key
* 通过3种方式设置tab key：1、使用router query参数pageKey 2、使用路由meta参数fullPathKey设置使用fullPath或path作为key
* 单个路由可以打开多个标签页
* 如果设置fullPathKey为false，则query变更不会打开新的标签（这很实用）

* perf: perf the control logic of Tab

* perf: perf the control logic of Tab

* 测试用例适配

* perf: perf the control logic of Tab

* 解决AI提示的警告
