feat: Allow passing id in DB hook create (#3048)

* feat(database-hooks): Allow passing `id` in DB hook `create`

It's the same to using a custom `idGenerator`, except configurable by the database hook which would in theory provide more data.

A use-case is to generate the id based on user info in the user before DB hook.
