The MDL view with invalid SQL will fail the query

[goldmedal]

Description

If the MDL has a view with invalid SQL, the query based on it will fail even if it doesn't use the invalid view.
The problem is that wren_core will plan all the view SQL when analyzing the MDL. So, if any view is invalid, the request will always fail.

Expected behavior

Instead of planning all the views, it's better to plan the views when they're used.

I found that the unused view will be filtered by ManifestExtractor. So, we won't occur this issue when the query through ibis-server.
