Fixes the bpred-sim.py to support command line parameterization of the branch predictor while using the new parameterization. This is definitely a hack, but I don't see a better way.

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.

Updated parameterization types. Modelsim version 2022.1 did requires defaults to a 32 bit integer. The base and ranges for the address decoder need to be larger.

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.
