LOG: [OpenMP] Use new OMPT state and sync kinds for barrier events (#95602)

This change makes the runtime use new OMPT state and sync kinds
introduced in OpenMP 5.1 in place of the deprecated implicit state and
sync kinds. Events from implicit barriers use different enumerators for
workshare, parallel, and teams.
