+per #15424 Added PersistentView, deprecated View

Browse source 
A PersistentView works the same way as View did previously, except:

* it requires an `peristenceId` (no default is provided)
* messages given to `receive` are NOT wrapped in Persistent()

akka-streams not touched, will update them afterwards on different branch

Also solves #15436 by making persistentId in PersistentView abstract.

(cherry picked from commit dcafaf788236fe6d018388dd55d5bf9650ded696)
