refactor: remove async loading logic for editor (halo-dev#6707)

#### What type of PR is this?

/area ui
/kind improvement
/milestone 2.20.x

#### What this PR does / why we need it:

取消异步加载默认编辑器，在之前的版本中，由于编辑器体积较大，所以做了异步加载的处理，但近期的版本中，为了让插件可以使用编辑器或者扩展编辑器，已经将编辑器依赖作为全局加载，如果这个时候还是异步加载编辑器组件的话，进入编辑页面的时候出现短暂的灰屏闪烁。

#### Does this PR introduce a user-facing change?

```release-note
优化默认编辑器的加载方式，防止出现灰屏闪烁的问题。
