The configuration of the `MonopoleLooperKiller` missed being updated
in the last update of the configuration syntax of `G4UserActions`.
This means that monopole simulation jobs fail in 21.0.37.
This commit updates the syntax such that the jobs should now succeed.
Should fix ATLASSIM-3440.

A number of different ways of configuring UserAction Tools were tried.
This merge request attempts to migrate all syntax to use simFlags.OptionalUserActionList

Contains updates for ATLASSIM-3023

Rather than having a ToolHandle to the `TrackFastSimSDTool`, the
`NeutronFastSimTool` is given the name of actual `TrackFastSimSD`
instance to be retrieved. This gets around the issue that the
`TrackFastSimSDTool` is no longer public. It means that the
`NeutronFastSimTool::initialize` method is now redundant also.
Should fix ATLASSIM-2813

Removed `DummyVolumeName` from volume list of `TrackFastSimSDTool`.
The current logic in `SensitiveDetectorBase` with the `noVolumes`
flag is sufficient to ensure the SD is added to the SD manager.

Private class data members should start with m_.

Clang warnings: unused class members, missing override keywords,
struct/class consistency.

Moving interfaces into a separate package from implementation code. ATLASSIM-1883

The idea behind these changes is to move towards making the Geo2G4
package into a pure component library. For this reason a separate
GeoMaterial2G4 package was created and headers used by other packages
were moved there. See ATLASSIM-1883 for details.

In the cases where both V1 and V2 implmentations are present, the V1
implementations can just be dropped. See ATLASSIM-3023
