Update the 2h/3h/4hpi0 and 2pi0 spruce lines

The Kspipipi0 lines were causing errors, it turns out the error was caused by the med_bpvipchi2_min in make-bbaryon_4body. In this MR:

For 3hpi0 spruce lines

• Set the med_bpvipchi2_min in make-bbaryon_4body to be None in lines
• Remove the sumIPCHI2 cut
• Tighten a bit the track selection with chi2dof_max <3 and ghostprob_max<0.5
• Change the photon and resolved/merged pi0 PID, same as those used in hhpi0 lines.
• Tighten the pi0 pt cut to 1.0 GeV(resolved) and 2.0 GeV (merged)

Spruce lines involved (6 lines in total) and the rates (run over 371018 data events):

For 2hpi0 spruce lines

• Modified the resolved/merged pi0 neutral PID selection, same as used in Hlt2 hhpi0 lines
• Tighten up the track selections, same as used in Hlt2 hhpi0 lines
• Remove the sumIPCHI2 cut
