nv2a: Implement vsh register carryover Uses nv2a_vsh_cpu to calculate the programmable vertex shader output of provoking vertex in order to implement the fog register carryover observed in Blade 2 and other titles. Hardware testing seems to indicate that carryover is specific to `oFog`, though I'm suspicious that this is really the case. For now I'm limiting this change to fog since that seems to be the only known problematic case.
