As discussed in ATLASRECTS-2953, in order to be able to drop the dependency on
the `TrkParameters` package from AthSimulation, then we need to move
`ITRT_ActiveFractionSvc.h` and `TRT_ActiveFractionSvc.h` out of the
`TRT_ConditionsServices` package. The first step is to move the interface elsewhere.

Drop the ZH prefix from the `FCS_StepInfoCollection` names.

Rather than writing out both `ISF_FCS_Parametrization::FCS_StepInfoCollection_ZHEventSteps`
and `ISF_FCS_Parametrization::FCS_StepInfoCollection_ZHMergedEventSteps` - only the
latter should be written out.

Production of DQ Web display for Tile Calorimeter
for collisions and cosmics runs is fixed.
Because new Tile monitoring used now is not compatible
with current Tile DQ configurations for these runs.

`G4Step` owns the pointers to the pre and post step point `G4StepPoints`
objects and deletes any existing objects as part of the
`G4Step::SetPreStepPoint(...)` and `G4Step::SetPostStepPoint(...)` calls.
Therefore deleting those pointers just before causes a double-delete
when the methods are called. This causes random crashes during the
simulation job.

Two missing `break` statements were causing the `m_detectormap`
member variable to be filled incorrectly.

It would be nicer to fill `m_detectormap` at the start of each job, rather
than on-the-fly, but this would require a major re-write.

Renaming `NeutralinoToPhotonPlusGravitino` tool to
`NeutralinoToPhotonGravitino` to match the naming convention used
by the other decay tools.

`ISF_FastCaloSimParametrization_DigiTilePreInclude.py` is identical
to `ISF_FastCaloSimParametrization_DigiPostInclude.py`. The configuration
should be done at the postInclude stage, so removing the preInclude.
