Add back the space-point element IDs to the transient data structure.

Levi Evansrequested to merge
leevans/athena:EFTrackingFPGAIntegration_fix_sp_elementID into main

This MR adds back the space-point element ids in EFTrackingTransient.h, which were accidentally removed in !78695 (merged).

Furthermore, the PassThroughTool has been moved to the build configuration that does not require OpenCL.

Lastly, the flag initialisation has been updated in the DataPrepConfig, since the addFPGADataPrepFlags method in IntegrationConfig now takes flags as an argument.
