fast-track highPrio+topValue validations

[metachris]

📝 Summary

Allow fast-tracking of highest value bids from high-prio builders (round robin (1:1) with regular high-prio bids).

• Fast-track-queue is supported by prio-load-balancer since v0.5.7
• Backwards compatible with previous prop-load-balancer versions (just using existing high-prio + low-prio behavior)

✅ I have run these commands

• make lint
• make test-race
• go mod tidy
• I have seen and agree to CONTRIBUTING.md
