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.

Enable a gem5 system to be an SST::Component.
This change includes,
- SST::gem5Component: responsible for,
- initializing the Python environment for gem5
- instantiating gem5 SimObjects
- connecting SST::SSTResponderSubComponent to
gem5::OutgoingRequestBridge
- hanlding the gem5 event queue (no thread-synchronization)
- handling executing gem5 events
- SST::SSTResponderSubComponent: responsible for,
- receiving gem5 requests and sending the requests to
memory.
- sending responses to the corresponding
gem5::OutgoingRequestBridge.
- SST::SSTResponder: owned by SSTResponderSubComponent, the
actual actor that sends gem5's requests to memory.
- gem5::OutgoingRequestBridge: receives the requests from
gem5 and sends them to SST. This SimObject allows the initialization
requests to be cached and the receiver could query the
initialization data later on.
- gem5::SSTResponderInterface: the interface specifying how SST
communicates with gem5.
- A working example of a gem5/SST setup.
More information is available at ext/sst/README.md.
