feat(CardDAV): Add Sabre\DAV\IMoveTarget support to OCA\DAV\CardDAV\AddressBook

This allows to just UPDATE the card row instead of deleting it and reinsert it. It's very similar to https://github.com/nextcloud/server/pull/30120 for calendars.

As we need the addressbookid exposed, this introduces OCA\DAV\CardDAV\Card that extends Sabre's.

I chose specifically NOT to auto-inject LoggerInterface in Addressbook like in #30120 because the chain of DI is huge just for ONE simple call and it would break an existing dirty call (OCA\Contacts calling OCA\DAV) of ContactsManager in Contacts: https://github.com/nextcloud/contacts/pull/1722 (in SocialApiService), but this is debatable.
