[charm/hyperons] use OWNPV functors for basic particles
Cherry-picked from !2886.
No new lines added or selection values changed. The warning from the original MR applies:
MINIPCHI2(pvs)
goes toOWNPVIPCHI2
, this is technically a different observable (OWNPV based on IP not IPCHI2)
So the retention / BW might change a tiny bit, but the quantity makes more sense if it's defined like this, especially for long lived particles.
