Log both request and response in trace logger
...
Inside DPI code, have a vector of unique_ptrs that act as handles to multiple
different trace logger instances. Each logger instance is instantiated in a
single instance of the Verilog module, and multiple of these Verilog modules may
be instantiated in the Chisel module (see simReq and simResp in MemTraceLogger).

Connect TL edge data to SimMemTraceLogger

TODO: since TileLink rounds all address down to a multiple of its beat
size (8 in the current code), we can't directly compare the memory trace
input to its output. Need to take masks into account.
