The HIP runtime is now allocating the hip_api_data and record on its
stack so we don't need the thread local record_data_pair stack anymore.
Refactor the API callback function to handle both the case where
synchronous user callbacks are requested and the case where asynchronous
records are requested (enable_callback & enable_activity respectively).
If the callback argument (memory pool) is not null, then activity
records are requested.
Remove CorrelationIdRegister and CorrelationIdLookup. These were used
by the HIP runtime to associate a HIP record id to a ROCtracer
correlation id. Instead, the HIP runtime is now using the correlation
ID returned in the hip_api_data_t.
Added a test to check enabling/disabling concurrent callbacks and
activities.
