### What changes were proposed in this pull request? PR #15764 disabled creating permanent views based on temporary views or UDFs. But AlterViewCommand didn't block temporary objects. ### Why are the changes needed? More robust view canonicalization. ### Does this PR introduce _any_ user-facing change? Yes, now if you alter a permanent view based on temporary views or UDFs, the operation will fail. ### How was this patch tested? Add new unit tests. Closes #33204 from jerqi/alter_view.
