  [flang][OpenMP] Move privatizations out of sections (#88191)

Besides duplicating code, privatizing variables in every section
causes problems when synchronization barriers are used. This
happens because each section is executed by a given thread, which
will cause the program to hang if not all running threads execute
the barrier operation.
