f9a89e6b - [OpenMP][FIX] Allocate per launch memory for GPU team reductions (#70752)

[OpenMP][FIX] Allocate per launch memory for GPU team reductions (#70752) We used to perform team reduction on global memory allocated in the runtime and by clang. This was racy as multiple instances of a kernel, or different kernels with team reductions, would use the same locations. Since we now have the kernel launch environment, we can allocate dynamic memory per-launch, allowing us to move all the state into a non-racy place.
