Remove Phys/DecayTreeTupleANNPID

Try to do !802 (closed) but piecewise - a full removal of all tuple tools in one go is effectively impossible. Follows from recent discussions around the clean-up of superseded code and tools and the retirement of the Phys project. See also !802 (comment 4771563).

Addresses part of lhcb-dpa/project#7, continuing from !820 (merged) and !821 (merged).
