Make object performance and rate plots from P2GT objects

All P2GT objects correspond to some L1 objects we are already using in the validation. We should thus be able to reproduce the same plots with the P2GT objects. This will eventually become the baseline as these are the objects used by HLT.

In addition this check will allow x-checking that P2GT and L1 objects are identical (or find discrepancies).

The parts where P2GT objects should be used are:

• Object performance turnons/trigger efficiencies
• Object rates
• Menu table
