Moved the rvvisynth code to testbench since I only want this for simulation and fpga.

Have rvvi to ethernet working.
...
Now it is time to move the hardware to the FPGA.
Ideally I don't want Wally to actually have any of this code since it's entirely
debug code so it will move to the fpga/src directory.
Then we'll need to add additional logic to the mmcm to generate the correct clocks.
Finally we'll update the I/O to add ethernet.

We have a simulation of the ethernet transmission working.
...
This commit does not include the source files for the ethernet as it does not belong to cvw.
I'll want to fork that repo and make it a submodule as I need to change the source a bit.

Successfully added RVVIStall for back pressure to slow down the pipeline if the ethernet or host computer running imperasDV can't keep up.
