Move packages from Phys to Analysis
Move Phys/DaVinciDecayFinder while keeping history. Followed @rmatev's instructions at https://codimd.web.cern.ch/Zh5o8aTeREetQrlA1Th_UA# .
Phys/DaVinciDecayFinder, Phys/DaVinciTools are not needed in Moore and can therefore be moved to Analysis.
This is the big merged MR, that also does !750 (closed) and !749 (closed)
The corresponding removal MR in Phys is Phys!873 (merged).
A fourth package, Phys/DSTWriters, is to be included too, but causes merge conflicts to be inspected by @rmatev.
