[OPENMP][NVPTX] Add support for lastprivates/reductions handling in SPMD constructs with lightweight runtime.
Summary:
We need the support for per-team shared variables to support codegen for
lastprivates/reductions. Patch adds this support by using shared memory
if the total size of the reductions/lastprivates is <= 128 bytes,
then pre-allocated buffer in global memory if size is <= 4K bytes,or
uses malloc/free, otherwise.
