Fix inconsistent pile-up decorations
We recently discovered that pile-up decorations are inconsistently done for MC and data (ATEAM-672). This MR tries to fix that:
- rename the decorations and all clients to be consistent with
xAOD::EventInfo
(thanks @tsulaia) - add
NoPileUpMuWriter
to just decorate zeros for MC without pile-up
I can run q221
and q440
fine locally.
Labelling urgent as this is needed for new samples production.
