Update MET TVA working point

William Keaton Balunas requested to merge wbalunas/athena:metTVA-220331 into master

This updates the track-to-vertex association working point used for some pieces of MET reconstruction to a new recommendation Nonprompt_All_MaxWeight (previously was a deprecated R21 one). I believe this only affects track MET: the track soft term in normal MET is currently subject to

  • Whatever the charged hadron subtraction for PFOs uses (currently already Nonprompt_All_MaxWeight), in the case of PFlow MET
  • d0 < 2mm and z0sinTheta < 3mm (equivalent to the R21 Nominal WP) for non-PFlow MET. I haven't changed this here; I suspect it won't matter much in practice since the recommendation will be to always use PFlow MET in R22.

This should resolve ATLASRECTS-6151.

Tagging @hpacey, @miholzbo, @sawyer, @schaarsc for awareness.
