DSLX feature request: Display proc hierarchy in traces

I would like to request that the process' owner and full hierarchy can be printed with `trace` or `trace_fmt`. The added functionality could work exactly like the Verilog $display %m option. It is desirable to be able to tell processes apart (also when they are on the same hierarchy level).

This would help debugging, e.g. in cases that spawn multiple instances of RAM and we want to quickly trace their contents and identify which trace comes from which instance.
