Get the program architecture information which has been associated with this 
datatype manager.  If {@link #getProgramArchitecture()} returns null this method
may still return information if the program architecture was set on an archive 
and either {@link #isProgramArchitectureMissing()} or 
{@link #isProgramArchitectureUpgradeRequired()} returns true.
@return program architecture summary if it has been set
