New Muon Origin Class and some fixes

This MR adds a class to ftagTruthMuonOriginLabel called NotInnerDetectorMuons and corrects an inconsistency by including the InDet::TrkOrigin::OtherSecondary class in the InDet::ExclusiveOrigin::OtherSecondary label.

Specifically:

• The new class for the origin of muons is useful because many muons in jets are reconstructed with ID tracks that correspond to the parent particle that generated them. This process occurs even for tight WP in muon selection. Until now, these muons were erroneously labeled as primary because, at the truth level, the particle associated with the ID track was often a hadron from the Parton Shower, and thus the origin was considered primary.
• Regarding the InDet::TrkOrigin::OtherSecondary class, it included all decays of long-living particles excluding (pions, kaons and Λ). The number of such decays is small, and these were previously labeled as primary. Now, they are correctly added to the InDet::ExclusiveOrigin::OtherSecondary label.
