Switch off extension of InDetCandidates in muon trigger when not needed
Switching off the extension of the InDetCandidates by default for the trigger, and ading the MuonInDetToMuonSystemExtensionAlg for when we run the inside-out reconstruction (only runs when we don't find any combined muons in a RoI). This saves a little bit of CPU (ATR-18811) without changing the muons we reconstruct.
