* Reworked Unit_hipLaunchCooperativeKernel_Basic and Unit_hipLaunchCooperativeKernelMultiDevice_Basic * Introduce reduction_factor for coop groups tests. Fix Unit_Coalesced_Group_Tiled_Partition_Sync_Positive_Basic * Fix always false requirement by adding a cast * Change data type to unsigned long long to align with cuda * Change literal type to double to ensure proper type casting * Remove formatting comments
