Muon truth overlay implementation (ATLASSIM-4007)

Tadej Novak requested to merge tadej/athena:overlay/truth into 21.0

It seems that we need muon truth overlay implementation as also pile-up truth is used in the truth matching algorithms.

A summary of this MR:

  • remove manual copying of the muon SDOs in the muon overlay algorithms
  • store all muon truth at pre-mixing (needs confirmation)
  • add muon truth overlay algorithms and enable them
  • also fix a typo in muon RDO analysis

The overlay algorithms are fairly trivial and the functionality was discussed with the muon experts (see comments).

The size increase of the pre-mixed RDO is about 2 %:

Disabling sweep as I will make the master MR more multi-threading friendly.
