Updates for muon trigger in new JO test

A few updates for the muon trigger in the new JO test (mostly related to the decoding):

• Turn on the seeded (RoI based) BS decoding for the trigger (including configuration of the Region selector which is needed for the seeded decoding)
• Removing the passing of the doTrigger variable to the decoding alg configurations, since we have an actual flag that we use elsewhere in the muon configuration.
• Refactor the decoding in the trigger configuration so that it can be used in two different steps of the muon triggers that run in different RoIs
• Fix a bug in the muon trigger TrackParticleCnvAlg configuration that was leading to a low efficiency of MS-only muons
