Refactored the fpga and testbench so the RVVI can be synthesized cleanly and simulated without any major code changes.
...
Adds three new configuration parameters to control enabling the RVVI packetizer and how much latency should exist between packets and the initial startup delay.

Wow. The newest version of Vivado does not like the enums as parameters.
...
The solution is simple. I changed the type to logic [31:0] and defined macros for the branch predictor types as 32 bit integers.

Got the branch predictor parameterized using Lim's method. Also had to add a global enum included in both cvw.sv and the configs which defines the branch predictor types. This should be synthesizable, but I'll need to double check.
