configs,ext: Updated the gem5 SST Bridge to use SST 13.0.0

This change updates the gem5 SST Bridge to use SST 13.0.0. Changes
are made to replace SimpleMem class to StandardMem class as
SimpleMem will be deprecated in SST 14 and above. In addition, the
translator.hh is updated to translate more types of gem5 packets.
A new parameter `ports` was added on SST's side when invoking the
gem5 component which does not require recompiling the gem5
component whenever a new outgoing bridge is added in a gem5 config.
