Clean-up Simulation CMakeLists.txt files

This merge request is a general clean-up of the CMakeLists.txt syntax for Simulation packages - it is a pre-requisite for dropping the use of atlas_depends_on_subdirs(...) in a future merge request. It adds installed libraries for interface packages where they were previously missing and adapts client packages to use these new interface libraries. It also does this for the clients of TrackRecordLib which already existed. Finally it creates a separate Interface library for the public header in the ISF_Geant4Tools package.
