Reorganise scheduling of ComboHypoTools
First step of implementing ATR-23484.
We add a step-to-ComboHypo-configurator map to the Chain
object, defaulting to the last defined step, so that we can add it later in the configuration, when all steps have actually been placed.
Follow-up MR needed to switch signatures over to use this instead of placing their topos statically.
Needed to hide the ID includes in MinBiasMenuSequences, to avoid a crash in TriggerMenuMT_checkMenuPrimaries_ctest
due to include
not being defined.
