Muon truth overlay implementation for master (ATLASSIM-4007)
This is a master version of !20961 (merged) already merged in 21.0
A summary of this MR:
- remove manual copying of the muon SDOs in the muon overlay algorithms
- store all muon truth at pre-mixing
- add muon truth overlay algorithms and enable them
- also fix a typo in muon RDO analysis
