Histograms of dR between different objects.

Add the dR between the following objects:

• 2 leading jets (both normal and PF variations)
• leading jet (both normal and PF variations) and leading photon

The following functions were added to help with this:

• TrigTLAMonitorAlgorithm::fillDeltaRHistograms that calculates the dR between two xAOD::IParticle and fills the corresponding histogram.
• TrigTLAMonitorAlgorithm.histdefs_dR that returns histogram definitions for two particles
