Add support for Scoping Events

Currently only normal emits are displayed, emits such as emitUp, emitTo and emitSelf are not recorded and displayed.

But we also need this ;)

[place where it is?](https://github.com/beyondcode/livewire-devtools/blob/709cf631968da4ccfb5c9059f38cae1ccc947326/src/backend/events.js#L39)

从 src/backend/events.js 的第 39 行附近开始，这里会记录普通 emits 以供显示，并跟踪事件数据如何到达 DevTools UI。扩展现有的事件处理以涵盖 emitUp、emitTo 和 emitSelf，然后验证每个具有作用域的事件都已被记录并显示。

由索引模型根据 Issue 内容生成。
