Content and media type CRUD controllers and services (#14665)

* Add GetAsync method

* Fix up delete document type controller

* Add scope to delete async

* Add some scaffolding

* Add create model

* Start working on validation

* Move validation to its own service

* Use GetAllAsync instead of GetAsync

* Add initial composition support

Still need to figure out some kinks

* Validate compositions when creating

* Add initial folder support

* Initial handling of generic properties

* Add operation status responses

* Move create operation into service

* Add first test

* Fix issued shown by test

* Ensure a specific key can be specified when creating

* Rename container id to container key

Let's try and be consistent

* Create basic composition test

* Ensure new property groups are created with the correct key

* Add test showing property type issue

* Fix property types not using the expected key.

* Validate against model fetched from content type service

Just to make sure nothing explodes on the round trip

* Make helper for creating create models

* Add helper for creating container

* Make helper methods simpler to use

* Add test for compositions using compositions

* Add more composition tests

* Fix bug allowing element types to be composed by non element types

* Remove validators

This can just be a part of the editing service

* Minor cleanup

* Ensure that multiple levels of inheritance is possible

* Ensure doctype cannot be used as both composition and inheritance on the same doctype

* Ensure no duplicate aliases from composition and that compositions exists

* Minor cleanup

* Address todos

* Add SaveAsync method

* Renamed some models

* Rename from DocumentType to ContentType

* Clarify ParentKey as being container only + untangle things a tiny bit

* Clean out another TODO (less duplicate code) + more tests

* Refactor for reuse across different content types + add media type editing service + unit tests

* Refactor in preparation for update handling

* More tests + fixed bugs found while testing

* Simplify things a bit

* Content type update + a lot of unit tests + some refactor + fix bugs found while testing

* Begin building presentation factories for mapping view models to editing models

* Use async save

* Mapping factories and some clean-up

* Rename Key to Id (ParentKey to ParentId)

* Fix slight typo

* Use editing service in document type controllers and introduce media type controllers

* Validate containers and align container aliases with the current backoffice

* Remove ParentId from response

* Fix scope handling in DeleteAsync

* Refactor ContentTypeSort

* A little renaming for clarity + safeguard against changes to inheritance

* Persist allowed content types

* Fix bad merge + update controller response annotations

* Update OpenAPI JSON

* Update src/Umbraco.Cms.Api.Management/Controllers/DocumentType/DocumentTypeControllerBase.cs
