Change layout ara(mac-phonetic) to ara(mac-phonetic-nodeadkeys)
The newly created layout misses a hamza dead key. Since this dead key is not yet available, make clear the layout has no dead key.
Added a TODO to remind to add the dead key variant ara(mac-phonetic) when the hamza dead key will be available.
Original issue: #296 (closed); original MR: !549 (merged).
