systemc: Implement sc_get_current_process_handle's other personality.

Browse Source 
When run during simulation, sc_get_current_process_handle returns a
handle for the currently running process or a invalid handle if no
process is running (ie sc_main is running).

When run during elaboration, it returns a handle to the most recently
created process. This second context is what this change handles.
