ElPointerProxyHandler class

在小部件树中较高层级创建一个代理事件小部件，它会代理后代 ElPointerProxy 的命中测试， 解决 hitTestSelf 被剔除的事件命中问题：https://github.com/flutter/flutter/issues/75747

注意：不要无脑将所有代理小部件都指向根节点，因为命中测试执行频率非常高，在桌面端，鼠标只要放在上面即使不进行任何操作， 每秒钟都会重复执行几十上百次 hitTest 方法，这也是为什么 Flutter 官方死活不愿意修复此问题， 甚至觉得添加一个 bool 判断都会影响性能。

请尽可能在局部需要的地方添加代理，可以在根节点添加，只是不要全部指向根节点就行。
