Add exclusion filter setting to typefinder settings (#14426)

* Obsolete constructor with deprecated IScopeProvider

* Add exclusion setting to typefinder settings

* The old TypeFinder constructor calls the new constructor now instead and excluded duplicates by using Union instead of Concat.

* Revert "The old TypeFinder constructor calls the new constructor now instead and excluded duplicates by using Union instead of Concat."

This reverts commit 87801c6c1cbaa6adab6f29dba1e876a586e05885.

* Add changes to TypeFinder

* Do not use null when type is not nullable
