Remove the use of UninterruptibleLockGuard in OplogBatcher, ReplicationCoordinator, and ReplicationCoordinatorExternalState

      We'd like to remove the UninterruptibleLockGuard because it is error-prone and adds complexity.

      Three pieces of replication code use the ULG today:

      • The oplog applier batcher uses it to do a read of the oplog to check it's max size before batch application
      • the replication coordinator uses to guarantee re-acquisition on the RSTL on the event of stepdown failure
      • the replication coordinator external state uses it to make storing the local last vote document uninterruptible

      We'd like to remove these usages to remove the ULG entirely.
