Update photon conversion definition for Run-3 by exclude TRT
This MR updates the photon conversion definition due to the Run-3 TRT issue [ ATLASEG-330]. Two major modifications are made.
- The isConvertedPhoton is modified in PhotonxAODHelper and EgammaxAODHelper to return an unconverted photon if a TRT-converted photon is passed. The function uses an excludeTRT to apply the new changes.
- The egamma tools are updated to consider the new definition, a flag excludeTRT is switched on if the run number is >= 410000 (Run-3 only). This follows the same MR: MR Please @gunal @ludovica review this.
