* Fix cooperative launch APIs to set hipGetLastError Previously, the cooperative launch APIs did not properly log their errors in the global hipGetLastError variable before returning back to the user. As such, the APIs would leave hipSuccess in the last error, which would break some use cases. This fixes that problem by making a trampoline function that does the HIP_INIT_API and ihipLogStatus. * Add missing flag to the log of multi-GPU launch
