  [OpenMP] Provide a specialized team reduction for the common case (#70766)

We default to < 1024 teams if the user did not specify otherwise. As
such we can avoid the extra logic in the teams reduction that handles
more than num_of_records (default 1024) teams. This is a stopgap but
still shaves of 33% of the runtime in some simple reduction examples.
