vcacheoptimizer: Update score tables using DE run

New tables are retuned using differential evolution, ran over ~1 day on
a 96-core GCP machine. The results are ~0.6% better than the table we
used to have across AMD & NV GPUs.

Also switch default population size to 95 - 100 elements don't
parallelize well across 96 cores which results in poor utilization.
