perf: improve `destroyOnClose` for `VbenModal` (#5935)

* perf: 优化Vben Modal destroyOnClose，解决destroyOnClose=false，Modal依旧会被销毁的问题

影响范围（重要）：destroyOnClose默认为true，这会导致所有的modal都会默认渲染到body
radix-vue Dialog组件默认会销毁挂载的组件，所以即使destroyOnClose=false，Modal依旧会被销毁的问题
对于一些大表单重复渲染导致卡顿，ApiComponent也会频繁的加载数据

* fix: modal closing animation

 - `VbenModal` 组件对与参数的处理优先级是 `slot` > `props` > `state`(通过api更新的状态以及useVbenModal参数)。如果你已经传入了 `slot` 或者 `props`，那么 `setState` 将不会生效，这种情况下你可以通过 `slot` 或者 `props` 来更新状态。
 - 如果你使用到了 `connectedComponent` 参数，那么会存在 2 个`useVbenModal`, 此时，如果同时设置了相同的参数，那么以内部为准（也就是没有设置 connectedComponent 的代码）。比如 同时设置了 `onConfirm`，那么以内部的 `onConfirm` 为准。`onOpenChange`事件除外，内外都会触发。
-- 使用了`connectedComponent`参数时，可以配置`destroyOnClose`属性来决定当关闭弹窗时，是否要销毁`connectedComponent`组件（重新创建`connectedComponent`组件，这将会把其内部所有的变量、状态、数据等恢复到初始状态。）。
 - 如果弹窗的默认行为不符合你的预期，可以在`src\bootstrap.ts`中修改`setDefaultModalProps`的参数来设置默认的属性，如默认隐藏全屏按钮，修改默认ZIndex等。
