Add EventInfoCnvAlg to AthSimulation Project
After the changes in !20912 (merged) it was found that Event/xAOD/xAODEventInfoCnv
needed to be added to the AthSimulation
project to prevent unit
test failures. This package requires the Event/xAOD/xAODCnvInterfaces
package, so that was added also.
Some tweaks had to be made to the Event/xAOD/xAODEventInfoCnv
to hide
dependencies on packages which are not part of the AthSimulation project.
