   * perf: Make every gossip thread use its own randomness instance, reducing contention (cometbft#3006)
   
   Closes cometbft#3005
   
   As noted in that issue, we currently are doing extra CPU overhead and
   mutex contention for getting a random number. This PR removes this
   overhead by making every performance sensitive thread have its own rand
   instance.
   
   In a subsequent PR, we can cleanup all the testing usages, and likely
   just entirely delete our internal randomness package. I didn't do that
   in this PR to keep it straightforward to verify.
