In WT-9042, the WT code to set the global timestamps was simplified, but also changed to eliminate possible races and to validate the final state of the timestamps. Running an MDB server build reported some errors.

There are complaints about setting the oldest timestamp after stable, here's an example from replica_sets_large_txns_format_2_enterprise-rhel-80-64-bit-dynamic-all-feature-flags-required, at: https://logkeeper.mongodb.org/build/3f81046
