Hansung Kim 630d76461c Do proper TL sourceId allocation for Vortex dmem requests 
This fixes sourceId collision that occurs when naively re-using tag bit
of a Vortex dmem request as TL source, which happens because Vortex core
does not allocate a new LSU entry for writes.

`VortexSourceGen` module acts as a Vortax tag <-> new TL source ID
converter, where it allocates a new ID for every new Vortex request, and
restores its original tag bits from the metadata embedded in the
SourceGenerator module.

TODO:
- Decouple sourceWidth of downstream TL nodes from Vortex's tag bit
  width; they are set to be the same for convenience as of now
- Apply this to imem requests as well

Hansung Kim a424f92b55 Make MemTraceDriver no longer be UnitTestModule 
This makes it trickier to hook the driver up to sbus since we need to
assert its io.start.  We still need io.finished coming out of it to tell
when the trace finished.

logger.

Hansung Kim af01e39b5a Revamp dataflow between uncoalescer and inflight table 
Now uncoalescer no longer handles constructing and enqueueing entries
to the inflight table; it simply queries the table and works with the
found row.  Enqueueing / looking-up of the table is clearly split
between request and response flow.
