TYPO3 Core

With #92289 logic has been decoupled from `ResourceFactory`
into the `StorageRepository`. As a side change, native php
typeing has been added to a couple of methods.

`StorageRepository->findByUid()` paramter type has been set
to integer, which breaks the `null` fallback and retrieving
the default storage `uid: 0` in `ResourceFactory` method
`getStorageObjectFromCombinedIdentifier()`. Even worser is
the fact that `getObjectFromCombinedIdentifier()` does not
even try to cope with a invalid provided identifier.
