[fix](lateral-view) Error view includes lateral view (#9530)

Browse Source 
Fixed #9529

When the lateral view based on a inline view which belongs to a view,
Doris could not resolve the column of lateral view in query.
When a query uses a view, it mainly refers to the string representation of the view.
That is, if the view's string representation is wrong, the view is wrong.
The string representation of the inline view lacks the handling of the lateral view.
This leads to query errors when using such views.
This PR mainly fixes the string representation of inline views.
