Removing the functionality to calculate the muon trigger isolation using FTK tracks and L2StandaloneMuons from the muon trigger isolation tool and associated algorithms (ATR-20766).
Also removed some obsolete functions leftover from Run 1 (using TrigMuonEFInfo object), and removed some unneeded include statements.

Removing the FTK muon isolation also from the menu code (and removed the other muon related FTK chains from the physics_pp_v7_primaries menu), so that no one tries to use this when it isn't supported.
