Persist muon hits in SelReports

The goal of this MR is to add muon tracks to the event model and persist muon hits in the SelReports. This has two major uses:

1. Information about the muon hits can be used in HLT1 selections, such as the number of muon hits shared between two tracks.
2. The stored hits can be used to study the IsMuon decision in the downstream software.

The muon tile IDs are now recorded as part of the IsMuon algorithm. If multiple hits are found in a station, only the hit closest to the track extrapolation (normalized by the tile dimensions) is kept.

To-do:

• Create a consolidated muon event model
• Save muon tile IDs in IsMuon
• Create consolidated muon track views
• Add muon segments to BasicParticle
• Fix validation sequence, which now gives a segfault on the CPU

Should be tested with LHCb!4413 (merged)
