V15: Utilizing content type filtering for navigation data instead of .OfType<T>() (#17639)

Browse Source 
* Implement GetContentTypeAliasForType which will replace the need for .OfType<T>();

* Refactor EnumerateAncestorsOrSelfInternal to be generic and extracting checks

* Add types to implementation referencing the old non-generic method

* Using

* Replace Ancestors.OfType<T> implementation

* Refactor EnumerateDescendantsOrSelfInternal to be generic

* Fixing references by adding IPublishedContent type param

* Cleanup + removing unused method

* Replace Descendants.OfType<T> implementation

* Remove unnecessary enumeration

* Updating Children.OfType<T>() implementation

* Adding correct types

* Fixing SiblingsAndSelf implementation

* Refactor TryYieldSelfOfType

* Remove nested checks

* Add comments and retrieval of content type alias from T in the private helper methods

* Simplify implementation based on review comments

* Add case when you get all root keys without a type

* Refactoring

* Renaming + review comments

* Rewrite SiblingsAndSelf
