Added Dxy plots (only for electron/muon at this moment)

[ryonamin]

Here is the "dxy" definitions used in the code:

(I modified variable names from the actual names just for explanation.)

1. gen dxy :
   const math::XYZPoint & vtx = genParticle.vertex();
   float phi = genParticle.momentum().phi();
   float dxyGen = ( - ( vtx.x() - beamspot->x0())sin(phi) + (vtx.y() - beamspot->y0())cos(phi));
2. reco dxy:
   float dxyRec = (electron/muon bestTrack)->dxy(beamspot->position());

This is the same changes as the PR#7884 but based on 75X release.
