What this PR does / why we need it:

修复在部分移动端浏览器（比如 iOS Safari）中，下拉框组件（VDropdown）的选项点击无效的问题，即没有触发 click 事件。此问题的原因可能是因为我们用的 floating-vue 组件提供的 v-close-popper 指令的兼容问题，最小复现：https://stackblitz.com/edit/vitejs-vite-ncpzhj?file=src%2FApp.vue

此 PR 改写了关闭下拉框的方式，不再使用 v-close-popper 指令，而且对其他使用此组件的地方没有破坏性更新。

Which issue(s) this PR fixes:

Fixes #3689
Ref #2699

Special notes for your reviewer:

如果有条件可以在移动端测试一下，尤其是 iOS Safari，目前在桌面端 Chrome 的设备模拟中测试正常。

Does this PR introduce a user-facing change?

修复 Console 端的下拉框组件选项在移动端无法正常点击的问题。
