#258 expose CPU/MEM AXI ports and connect them in Difftest. This change move the connect back to DUT inside when !isFPGA, and override `cpu <> mem` with `cpu <> cpuIO` and `mem <> memIO` when isFPGA with DifftestMemCtrl.exposeIO(cpuAXI,memAXI).

Previous #258 always expose CPU/MEM AXI ports and connect them in Difftest. This change move the connect back to DUT inside by default, and only override `cpu <> mem` with `cpu <> cpuIO` and `mem <> memIO` when isFPGA with DifftestMemCtrl.exposeIO(cpuAXI,memAXI).
