Merge cockroachdb#121948

121948: cli: deflake TestLossOfQuorumRecovery r=arulajmani a=pav-kv

LOQ tooling works poorly when nodes stop in the middle of a split/merge operation. Prevent test flakes by making sure the scratch range split completes on all replicas, before turning down the nodes and running the LOQ tool. Also, disable the split and merge queue.

Fixes cockroachdb#121547
Epic: none
Release note: none
