…ing 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. --- - [x] Tests written/updated - [ ] Changelog entry added in `.changelog` (we use [unclog](https://github.com/informalsystems/unclog) to manage our changelog) - [ ] Updated relevant documentation (`docs/` or `spec/`) and code comments - [ ] Title follows the [Conventional Commits](https://www.conventionalcommits.org/en/v1.0.0/) spec

Note I edited the v0.37.x gossip routine. This will need backporting to v0.38.x, it is on v1.x |
