Enabled profiling for CPU agents for memcpy activities

To be able to trace memcpy asynchronously, both dst and src agents need to have profiling enabled and the api for enabling profiling was only enabling for gpu agents. CPU agents didn't have profiling enabled so the signal owner could not be known. hsa_amd_profiling_get_async_copy_time will fail with an HSA status error because it can't read the agent for the given signal.
