[OPENMP]Use new interface for task reduction. Summary: Patch forces codegen to use the new runtime functions for task reductions where the issue with passing the address of the original variables to the UDR initializers is fixed. Also, this patch is required for upcoming support of task modifier inreduction clause.

[OPENMP]Fix PR45047: Do not copy firstprivates in tasks twice. Avoid copying of the orignal variable if it is going to be marked as firstprivate in task regions. For taskloops, still need to copy the non-trvially copyable variables to correctly construct them upon task creation.
